MILESIGHT - Soil moisture sensor IP65 - 3 in 1 - LoRaWAN

Milesight EM500-SMTC: IP65 3-in-1 LoRaWan soil moisture sensor

The EM500-SMTC is designed to measure soil moisture, temperature and electrical conductivity in harsh environments, and to transmit data using LoRaWAN technology.

Thanks to this low-energy technology, the EM500-SMTC can operate for up to 10 years on a 19,000 mAh battery.

Combined with a Milesight LoRaWAN gateway and the Milesight IoT Cloud solution, users can remotely manage and view all sensor data.

The EM500-SMTC is widely used in outdoor applications such as smart agriculture, smart horticulture and more.

This device is designed to withstand the harshest environments. Thanks to its shock and vibration resistance, IP67 transceiver and IP68 sensor.
