Temperature/Humidity Sensors


I’m currently running a new Helium Dev Kit - Element (Ethernet), Atom Dev Board with Raspberry Pi Adapter and a RPi3. I’m looking to connect a temperature or temperature/humidity sensor.

Any pointers/links to what’s needed to accomplish this?

Note that temperature is more important than humidity.

Thank you in advance!


If you are using the standard Pi Adapter, you’ll find you are blocking the pins on the GPIO where you’d typically put sensors and the like.

If you’re just prototyping and don’t like soldering, you can do what I did, which is grab the USB Adapter (https://www.helium.com/products/atom-usb-adapters) and pop your Atom on there. That frees up the entire header so you can put whatever sensor board on there that suits. For example - The EnviroPhat - https://www.adafruit.com/product/3194 - gives you a whole host of sensors on a small board (and an analog port so you can attach analog sensors).

If you are up for the soldering then… there’s the super simple option of hanging a DS18B20 sensor off the Pi headers. This tutorial - https://www.modmypi.com/blog/ds18b20-one-wire-digital-temperature-sensor-and-the-raspberry-pi shows you how, without the adapter board on. Yes you could solder that onto the adapter board but another option is Pico Hat Hacker - https://www.adafruit.com/product/3577 - Then you can solder your sensor onto that.

Finally, you could just pop something like a USB Temperature Sensor into the USB port - https://www.amazon.com/Ebest-Thermometer-Temperature-Record-Laptop/dp/B009YRP906/ref=sr_1_3?ie=UTF8&qid=1506095787&sr=8-3&keywords=usb+temperature+sensor - like that and read that.
