Wireless thermal logger. Intended use is to help in thermally modelling a room.
Sensor nodes made using an STM32G0 MCU and connectivity options include
- nRF24L01+
- RFM95W/CW/TW
- RFM96W/TW
Sleep current is ~2uA
Aggregator is a simple ESP32 based dev board connected to nRF24L01+ (PA breakout board) in my case.
