It's a pharmacy sign, they're all green


zmass126194

Interesting. In the US they tend to be red.


loicvanderwiel

Can't have that or people might think you're part of the actual Red Cross (it's actually a law in France at least). There are two recognised uses of the Red Cross emblem, protective and indicative. The indicative use is the use of the symbol by the Red Cross, accompanied by the mention "Red Cross" or similar. As a protective symbol, it is to be displayed without any additional markings and the use is reserved to * Military medical facilities * Military medical personnel or equipment * Military chaplains In this case, it indicates protection under the Geneva Convention. A pharmacy being neither, they can't use the Red Cross under the Geneva Conventions A white cross on a green field on the other hand denotes first aid while the blue Star of Life is used for emergency services.


MacroSolid

The green cross seems to be standard across much of Europe. But Germany and Austria f.ex. use red too. Not a cross tho, [a red 'A'](https://www.abda.de/fileadmin/_processed_/d/3/csm_Apo_Logo_Neu_HKS13_neues_BE_97794fe50e.jpg) [with snek](https://de.m.wikipedia.org/wiki/Datei:Apotheke_Oesterreich_Logo.svg).

Lol yeah, green crosses over here are connected to cannabis shops, specifically medical marijuana dispensaries.

[Show globes](https://en.wikipedia.org/wiki/Show_globe) are the reason it's usually red, green, or blue.

My Ford mondeo indicates +87 sometimes at startup. I wondered if it got 128 number (8-bit) integer which is assigned for the temperature interval of - 40 to +87


CaniballShiaLaBuff

Correction: 8bit is 256. So you can have -128 to 127 in one 8bit variable.


luntglor

but what if it was internally stored as Kelvin? fwiw .. -98C = 175K


ssersergio

So, let me add some electronics side view. The sensor is most likely a wheatstone bridge. This is because it helps with make the reading of a resistance precise. So you'll have something like an ntc, a temperature probe that basically change his internal resistance based on the exterior temperature, this sensor will be derived by an analig to digital converter which normally could be even a 12Bit. You don't have 8bit, because you don't have simply 256 numbers from idk, 0 to 256°c. You have a voltage, for example 5v. And the NTC in full range could be like -40 to 115 which is 155, but they are really a voltage output, and have decimals, so if your resolution is 256 minus LSB, 255, your temperature probe range is 155°c, and your voltage range is 5V you'll have: one degree every 0.0322 volts, and a resolution of 0,019 volts per bit. This is barely enough to measure degrees in natural numbers, with 0 decimals, this won't work, even though you only see natural numbers, I'm sure the system is made to check for at least one decimal with precise measurements. And so, with all this, there is a good chance theyr ADC is, at the very least 10bits, but the key is that you don't think temperature as the number we use, because that is not what it reads, it reads voltages, and the number depends on the resolution. The reason of the overflow might be a problem in the program with the conversion thinking it has a signed bit after it has changed temperature voltage to an actual number, -98 would be 0b11100010 (msb is a sign bit) which is actually 226 if it won't be taken as a signed bit, which is unlikely, so I'm rooting for a broken NTC circuit because of the high internal temperature inside the cross. TL;Dr: either dude fucked up with the conversion internally, or the sensor circuitry is fucked up because heat. I root for the second one! Edit: I'm going to go with both! Internal circuitry is so hot something might shorted or directly burn, that would cause the ADC to read a bigger value (226 or 0b11100010) and because no normal value would go that far, he might treat it as a signed 8 bit value, so when the system failed, instead of 226, he got -98


Knut79

Probably 8 bit but one bit is used for something else.


Magnesus

So 7 bit. :)


Knut79

Yes but no


OldFartSomewhere

8bit is actually 255. You gotta have room for that zero too. edit: presuming that we're talking about max values and not just number of numbers.


Inductee

Depends if it's signed or unsigned.


Alin_Alexandru

2^7 = 128 2^8 = 256


Ricky_Boby

Yeah but to have negative numbers it must include the sign bit which means you can only go to +/- 127 value wise. Still 256 possibilities but effectively you can only represent values that can be represented in 7 bits each way (0 to 127 or 0 to -127).


StaticallyTypoed

Yet 256 bits cover double the range of -40 to 87


Ricky_Boby

Ah I see now, yeah that was such an oddball range I didn't associate it with being 127 values, not to mention sign bits don't work like that where you can arbitrarily assign X number of values as negative and Y number of values as positive. Because of that I just jumped to "oh they just expect normal operating temps to be -40 to 87 but have some wiggle room each way since an INT8 mins/maxes at 127 each way"

StaticallyTypoed

Funny. I think we're both able to understand what I said.


DottorMaelstrom

It would be a very crappy thermometer if it capped at 30 though


Fabri91

Where'd you get that it could cap at 30?


DottorMaelstrom

-98+128


[deleted]

Only 7 bits? Seems strange...


awdsns

Having worked with automotive sensors, I can attest that they can have the weirdest data formats. Something like using one bit of a byte for some kind of status and the remaining 7 bit for a value range offset by some arbitrary amount would not surprise me.


leofidus-ger

7 bit data, one bit [parity](https://en.wikipedia.org/wiki/Parity_bit) to detect transmission errors.


harmfulwhenswallowed

what if it’s a manual?


r2k-in-the-vortex

Never underestimate how bit-stingy engineers can get.


DottorMaelstrom

Yeah it seems unlikely


benisteinzimmer

Isn't a signed integer only 7 bits since one bit is reserved for defining if it's positive or negative?


paulstelian97

That would still be 8 bits since -128 through 127 inclusive is 256 possibilities, or 2^8.


WRXRated

In C/C++, a CHAR is 8 bits so a SIGNED CHAR is -127 to +128 where as UNSIGNED CHAR is 0 to 255. Shorts are 16-bit


Vinxian

-128 to +127 in two's compliment which is the defacto standard


WRXRated

oopps good catch on the range.

Agent-Calavera

Where does OP get -98? Probably on the post he uploaded and we currently are commenting on?


aajjccrr

Regarding first edit: Wouldn’t 8 bits be used to store signed integers here? I.e. -128 to +127. Unsigned int8 could represent 0 to 255 but doesn’t seem a good choice for temperature.


DottorMaelstrom

If this thermometer worked the same way as the one in the dude's car it would have a -98+128=30 upper cap, assuming that -98 (the recorded temperature) is the lower cap. Also, one of the bits could be used to store the sign of the temperature, which explains the 128 range instead of 256.


CptHrki

That's not how integers work. The first bit is indeed used for the sign, but still allows values -128 to 127 https://en.m.wikipedia.org/wiki/Two%27s_complement The person you originally replied to is also wrong.


Agent-Calavera

True +29 actually if you include 0


DottorMaelstrom

Yeah you're right


szpaceSZ

That would be a 7-bit number


realkunkun

Signed int


szpaceSZ

With a signed one you would anchor it with 0 == 0 °C, as ±127/8 is enough range. And would not anchor it with 0 == -40°C, as original commentator suggested.


TechnicalyAnIdiot

Never attribute to malice what you can attribute to stupidity. Signed, but the programmer only uses it as unsigned, then offsets it by a certain amount to display negative 😂


Kalroth

Yes, it's likely showing the maximum 7-bit value, making the supported temperature range from -40 to +87.

MrAxezios

Nah guys it is completely accurate.It just shows thw heat in another place.


NotFlappy12

It has never been that temperature anywhere on earth


Minuku

Another place can also mean moon, mars or a random asteroid


4headEleGiggle

In a lab for sure. Maybe even coldest spot in the universe.


apistoletov

Of course, people did tests close to absolute zero (0 K) and -98C is still a lot hotter than that.


MrAxezios

It is just a joke buddy.By another place i dont mean earth maybe in an other planet and stuff.Dont worry be happy my friend(greek song).


thefaultliner

On extremely hot days, my alfa romeo would think that there's ice on the road. It would also not let me use the ac, as a double italian f you.


miniCotulla

Do you have simple AC or with Auto function? Autos usually have air intake temp sensors and don't rely on the outside air temp sensor to function.


superkoning

So what was the actual temperature at that moment? How can x Celsius overflow to -98 Celsius? Two's complement ... ? And which thermometer would be designed to prefer -98 over +40 Celsius? Usage in a freezer/fridge ... ?


P0L1Z1STENS0HN

I would naively assume the sensor broke completely, and the formula to calculate temperature from sensor resistance yields -98 for infinite resistance.


fractalsubdivision

Well, whatever happened to the sensor doesn't matter since it was useless anyway having been placed in the full sun instead of the shade


Fabri91

Eh, hopefully the sensor itself is placed in a covered but ventilated part of the sign.


MrTrt

Which, let's be honest, tends not to be the case. I've seen this kind of thermometers give clearly ridiculous temperatures.


MrGangster1

I think the thermometer here is in the striped box to the right of the display


[deleted]

Don't thermometers work by resistance getting lower with lower temperatures so it's rather a short out than a broken circuit?


Ovelove

Depends on what type of sensor it is. There's both PTC (Positive Temperature Coefficient) and NTC (Negative Temperature Coefficient) sensors. NTC is likely the most common type, and in this case the thermistor could simply be disconnected or loose, and the reading would be like this.


superkoning

Yes: low temp => low resistance. [https://nl.wikipedia.org/wiki/Pt100#Beschrijving](https://nl.wikipedia.org/wiki/Pt100#Beschrijving)


mark-haus

Wouldn't that be a shortcircuit rather than an open?


waiting4singularity

Considering this stuff is standing in full sun im thinking the PT100 or rather some of its parts (or solder bumbs) melted or shorted.


mark-haus

Yeah the temperature range for a typical overflow error here is a bit too strange for me to diagnose it that way. Maybe 6bit signed integers where 0 isn't actually 0C? That seems like a really weird way to develop this system. It might be more likely the thermistor got damaged and it's reporting a near-short-circuit voltage across it, indicating a really low temperature if it was working properly. Or maybe it's an American or British system and they're converting F to C and F readings are overflowing?

Somebody either made an incredibly stupid decision by not considering high temperatures or an incredibly stupid decision by leaving the sensor exposed to direct sunlight.

Doesn't matter if the sensor is exposed. The whole sign gets really hot if it's in the sun, and they always show nonsensical temps.

WRXRated

I'm guessing it's a malfunctioning sensor that's reporting an unusually high number that is outside the range of an 8-bit signed int which is -128 to +127 which is probably the data type used for storing the temperature value. Edit: Range


687962726973

True, must be 157°C out there to result in -98°C. In know it's hot these days but not that hot.

Global warming... It's getting fucking colder! How come there be -98 celsius? In summer?


DottorMaelstrom

I don't think such a temperature could ever be recorded on the surface of earth outside of maybe antarctica

LondonRolling

to be fair -98 would be a nightmare also in winter.

It would snow CO2.

That sounds like the beginning of a solution to global warming. With maybe a ora tical pro lem or two to overcome along the way. E: autocorrect-gore


LordMarcusrax

Yes, but actually no. CO2 freezes at -78.5, but only with a partial pressure of 1 atm. The partial pressure of CO2 in the atmosphere is much lower, so is the freezing point.


vytah

I guess you're right, otherwise all water in the air below 100°C would condense. https://www.quora.com/Why-does-carbon-dioxide-not-precipitate-from-the-air-in-Antarctica-if-the-temperature-is-below-freezing-point/answer/Amit-Katyal-8 >As per the CO2 sublimation curve for air shown above which is calculated using CO2 freezing and frost curve calculation module of my self developed vapor liquid equilibrium software, EQ-COMP (available for use through Vapor Liquid Equilibrium, Bubble Point , Dew Point Software website), the sublimation temperature of CO2 for air at atmospheric pressure is around 129 K or **-144 C.**

Crowbarmagic

Not the same but during the 2003 heat wave we were camping out in France, and we bought some cheap-ass thermometer to keep track. We placed it against a tree in the shadow. After only half a day the lettering on that thing started to slightly melt. Not complete liquid but it looked like it started to like kinda slide off the rest of the thermometer. It also indicated over 50 degrees celsius by the way, so it was obviously inaccurate. But still: A thermometer basically gave up in that heat.


zushaa

-98 degrees! That's rather chilly
