Adding an Inside Climate Temp Sensor

[88GreenVN]

Thinking of making an inside temp sensor to add to the ambiant sensor.

So I made up a switch and second sensor and it almost worked. It will show the inside temp on start up and switch to outside once only and not go back to inside without turning off the ignision.

Now to find a better switch.

Got the extra sensor all wired in - now to get it to work all the time!! If you change from inside to outside it changes instanly - counting down 1 at a time until it hits the ambiant temp. But it then wont turn back to inside sensor. If you start with outside temp it will not change to inside.

Going to go test if I turn the unit off, change the setting, and then back on again - will it refresh the temp?

WE WANT PICS!!

Please

Some pic - not much to see yet

I've put the inside sensor under the driver's seat tucked into the back padding just a little to hold it in place. We'll see how that goes.

OK on the way to work today I checked the temp and thought I had left it set on inside sensor. Into the carpark and have a look - nope it's on the outside sensor - so I changed it and the temp changed too. (by 1 degree) So then when through the ignision on and off again to get the temp to change between inside and outside sensors. yep 1 degree difference between the inside temp and outside temp. (car was in the shade)

So it may be just that you need to let a little drive time go by between temp readings. Will have to go for a longer drive to test this out tonight.

Some longer runs have shown up the temp will go up slowly when flipped between inside and out side but fall instantly down 1 number at a time to the new sensor reading. There it stays until the car is turned off or some distance is travelled - yet to be worked out.

So I leave the car with it set to inside temp so when I get back to the car I have how hot the car is inside. Switch to outside temp and it will fall if cooler only.

So not perfict at all but workable for now.

Today (31/12/09) I had 52 inside the car and 40 outside. The inside temp sensor was inside the centre consol

nice work shane, i woulda loved to of known mine the other week when it melted my led warning lights

hmmm - this is why I'm working on this little project - just need to find the best spot for accurate readings on the inside.

this is a great idea. coould you post up a wiring diagram

based on my findings, just above the windscreen demister vents, tis atleast where it got hot enough to melt plastic and solder in my car

that is where the outside temp sensor is too. personally i think maybe under glovebox would be a good spot it will get hot still but should avoid most of the magnified heat type areas

noooo that's the sun sensor The outside temp sensor is bolted to the radiator support just in front of the aircon condensor

Will do as soon as I sort a better switch. Basicly I've just pliced in a second sensor cut out of a loom and put a switch into the main sensor loom.

pccies?

The road trip on Thursday went well.

Must be as part of the default settings that quick rises in temp are not counted. Outside was real hot and inside real cold = the A/C is working well. So when changing from outside to inside the temp dropped almost instantly. Try changing it back and it goes up every 5 mins or so by 1 degree. It then stays in this mode until the car is turned off. Once it has reached the ambient temp (on the out side setting) it works as it should and will read small increases and decreases.

So next step is to wire in a reset mode for whrn you change from inside to outside so it gets the new reading each time.

cool shane, i only realised i had an ambient temp setting on my cc after i saw this thread btw

Go directly to JAIL - donot pass go or collect $200. (no out of jail free cards)

im a windows down person, ive only used my climate control like 5 times
