Welcome to the piProbe wiki!
This project has a few hardware requirements, this is what I used.
- SanDisk 16GB Ultra microSDXC Class 10
- HiLetgo DHT22/AM2302 Digital Temperature And Humidity Sensor Module
- Raspberry Pi 3 B+
- Raspberry Pi 3 Model B/B+ Plus Power Supply 5V 3A
- Raspberry Pi 3 b+ Case, iUniker Raspberry Pi 3 Model B+
The case is obviously no required, but probably a good idea for a real world deployment.
Note: The DHT11 and DHT22 probes require that you solder a resistor onto the probe. The AM2302 is a DHT22 with the resistor already attached, so it does not require any soldering.
- Install the Pi into it's case
- Install the probe you've chosen, this is the GPIO Pinout configuration that I used: GPIO Pinout
- Install balenaEtacher on the computer you'll use to flash the SD card
- If you plan on using Balena, ensure that you have created an account at Balena.io
- If you plan on using Balena, ensure you have the balena-cli installed
Both methods assume you have an InfluxDB instance up and running somewhere on your network. Setting up InfluxDB is outside the scope of this Wiki.
This project is configured so that it can be easily deployed to a fleet of RaspberryPi 3/3+ nodes. This is by far the lightest weight option. I've been able to cut the container down to 32mb!

You can also manually install piProbe. This option will require more upkeep, and is a much heavier option to setup.
