SE02-NB NB-IoT Soil Moisture & EC Sensor 2 Probes
SE02-NB NB-IoT Soil Moisture & EC Sensor 2 Probes
The Dragino SE02-NB is a NB-IoT Soil Moisture & EC Sensor for IoT of Agriculture which has 2 sensor probes. It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses FDR method to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in factory for Mineral soil type.
It detects Soil Moisture, Soil Temperature and Soil Conductivity, and uploads the value via wireless to NB-IoT IoT Server.
SE02-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.
SE02-NB supports BLE configure and OTA update which make user easy to use.
SE02-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
