SensNode-LR-STM LoRaWAN® Soil Temperature and Moisture Sensor

SensNode LoRaWAN Soil Temperature and Moisture Sensor measures soil moisture and temperature at the range of 0 ~ 100% (m³/m³) and -40 ~ 80℃ respectively, making it widely applicable in soil sensing scenarios. It is specifically optimized for OTA with built-in Bluetooth, which enables quick setup and upgrade. Benefiting from LoRa and IP66 design, this sensor features stability and reliability and can cover a long transmission range while keeping lower power consumption. Unlike wireline devices, it is battery-powered, reducing the workload and complexity of the deployment, and can be disassembled and installed in a few minutes.
