2020 - battery powered irradiance remote sensing with LoRa IoT
From Apr-2020
An M&T irradiance sensor was modified with a analog data acquisition unit and a LoRa sender using standard components from Adafruit, as an Arduino feather, ADS1115 16bit ADC and RFM96W LoRa radio chip. An extra power board was needed for supplying the M&T sensor with 5V, which was changed with a later version using the unamplified analog signal and an INA219 shunt monitor as mV singal amplifier.
