  • temperature sensors

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

    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

      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:

              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.

                  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.

                      single line multiple temp sensors

                      IMHO: I2C single line temp sensors are the way to go. I've worked on different projects (I'm an EET) and these are pretty simmple to use. Each sensor gets programmed with an address so they can all use the same data I\O line. 3-pins 3-wires and you can connect a bunch.
                      Dallas semi makes a decent one (DS18B20) with a 64-bit ID code, in case you need that many

                        Any help on interfacing them (ds18B20's and ds1822P's) to a parellel port, game port, or serial port? Parellel would be prefered by me as what else am I going to use that port for (a printer...NO!). Second would be game port then serial (I already used my two up). I do have a usb to serial adapter but I'm trying not to use it because if I do then I'm going to need to buy a usb hub

                          There 's a solution with a 1-wire-USB interface too. And 1-wire can be used for other sensors than temp. But it's in French

                            Also this one that uses an AT90S2313 and talks to an ADC and temp sensor via Microwire.

                            I'm gonna try build it and write a serial port interface for it in the next few weeks..

                              As long as they are strictly SMBus you should be all set with the onboard SMBus (not I2C) connector on the EPIA boards. There doesn't appear to be a way to issue I2C commands on it.
