LoRaWAN T&H Sensor with External Illuminance Probe

A LoRaWAN sensor that combines built-in temperature and humidity measurement with an external illuminance probe. The probe can be placed where light matters — at a work surface, a greenhouse bench or a display shelf — while the main unit is mounted nearby. A built-in 2,400 mAh battery supports long unattended operation. On the NARA platform, light, temperature and humidity are charted together for lighting audits, energy management, greenhouses, warehouses and storage of light-sensitive goods, with alerts when levels leave their target range.
