Most Helpful Customer Reviews
I bought two for my fridge and freezer and they work great with my Raspberry Pi 3. I use the wiring-pi node library to poll both thermometers every 30 seconds, but I have tested polling them as often as 1 or even 0.5 seconds and it works fine. The metal probe and rubber cable seem high quality and unlikely to break. I soldered breadboard headers onto the ends of the wires to use with a Pi cobbler. I have the two red wires connected to 3.3v, two black wires to ground, and two wires green to BCM Pin #4, and I can read both temperatures with code on the Pi. A 4.7k Ohm resistor bridges the red and green wires.
I am using this with Arduino to track temperature in my aquaponics system. I am a newbie to Arduino, and found many of the tutorials on these to be confusing. A good tutorial can be found at http://goo.gl/LPG3Yf.
Works great. Only thing is including the pin-out / color code would be nice since you can't see which wires are attached to which pins of the chip with everything sealed up. At least for mine, red/black were +/- power, and green was data.
