Box for mysensors temperature and humidity sensor. The box holds the pcb board and a battery holder for 2 AA-batteries. For download I added: stl-files fort printing the box picture of the pcb-board schematics of the pcb front and back circuit diagram of the pcb software for the processor (ATmega328) To complete the pcd you need additionally: Atmega328, RFM69HCW, Si7021 or other temperature/humidity node. The software is capable for Si7021, but I also developped one for DHT22. In case you don't want to manufacture the pcb on your own, or have any problems in sourcing RFM69 or Si7021, please let me know. I'm always happy to help. Very low power consumption!!! Mine is running since 6 months using 2 AA-NiMH batteries, which are still at 1.2V each. It's at
