MYSensors temperature humidity sensor
thingiverse
I've created a box for my MySensors temperature and humidity sensor. The box holds the PCB board and a battery holder for two AA-batteries. For downloading, I've added STL files for printing the box, a picture of the PCB-board, schematics of the PCB front and back, a circuit diagram of the PCB, and software for the processor (ATmega328). To complete the PCB, you'll need to add an ATmega328, RFM69HCW, Si7021 or other temperature/humidity node. The software is capable of working with Si7021, but I've also developed one for DHT22. If you don't want to manufacture the PCB on your own or have trouble sourcing RFM69 or Si7021, please let me know. I'm always happy to help. This device has very low power consumption! Mine is running for six months using two AA-NiMH batteries, which are still at 1.2V each. It's already
