AgroSense Temperature & Humidity Sensor SHT31 – LoRaWAN

The AgroSense Temperature & Humidity Sensor (SHT31) is a high-precision LoRaWAN®-enabled environmental sensor designed for demanding agricultural and outdoor deployments. Featuring the SHT31 sensor, it accurately measures temperatures from -40°C to 125°C (±0.2°C) and humidity from 0% to 100% RH (±2% RH), with fine resolution (0.01°C/0.01% RH). Its IP68-rated enclosure ensures exceptional durability in harsh environments such as heavy rain, dust, or direct sunlight.



This sensor operates on the LoRaWAN® 1.0.3 protocol, enabling long-range (up to 5km line-of-sight) wireless data transmission with minimal power consumption. Powered by two AAA batteries, it offers up to one year of autonomous operation. Users can easily configure the device using provided LoRaWAN® credentials (DEV EUI, APP EUI, APP Key) and remotely monitor conditions through supported networks like The Things Network or DataCake. Ideal for precision farming, greenhouse automation, and remote environmental monitoring.
