temperature sensors

here's a couple links for anyone who might like to add
temperature sensors to their car, connected to your carpc:

http://www.lancos.com/webtherm.html

http://www.riccibitti.com/pc_therm.htm

for the sensors (ds1631),
Dallas Semiconductor was taken over my Maxim IC
maxim-ic.com
you can get a couple of them for free, by requesting free samples.

This is what I really want for a car PC temp sensor

But I can't find those sensor in the States

this one looks pretty neat
i bunch of them i've looked at retail at over $160, which IMO is rediculous, but $40 aint bad

I'd much rather just get one of these:

and a couple of these:

Wait a minute....there are about 8 million temperature sensing computer products designed for monitoring case temp, processor temp, RAM temp, disk temp, mouse temp, keyboard temp, porn site temp, etc etc etc....

One of those kind of things has to able to be converted easily and cheaply into an ambiant outside air temperature sensor.

Heck, I just use a 4 sensor serial circuit that requires no external power and no calibration (US$30), it is fully incorporated into my remake of Media Car... check out:

(there are links for the information and ordering locations on the links page)

This looks like the way to go. You basicaly get as many sensors as you want and it uses the SMbus (I2C) connector on the epia boards. One IC and you have 4 remote temp sensors 2 ICs 8 etc and the actual temperature sensor is a simple el-cheapo transistor. Best of all you don't use up a serial port.

Phidgets are great but their temp sensor seems a lot bigger than most of the other around.

That's awesome! although, with all my clumsiness and luck I'd probably fry my MB trying to get it in place.

Actually most mobo's have a 5 or 6 pin header that you connect a cable to. That way you can build the circuit on a breadboard plug in and go. Now if you don't have an SMbus/I2C connector you will need to solder a connection to your motherboard. I'm thinking that the most difficult thing here will be soldering the leads to the chip, it's tiny.

I'm waiting on parts to try this out. I'll post the results when I'm done.
