NPK-7in1 NB-IoT Soil NPK Sensor with Solar Panel

NPK-7in1 NB-IoT Soil Sensor for IoT of Agriculture. It is designed to measure the Soil Fertility Nutrient and provide a plant growing reference. The probe is IP68 waterproof and can be buried into soil for long term use.

NPK-7in1 NB-IoT sensor detects soil's Nitrogen, Phosphorus, Potassium, Humidity, Temperature, Electrical Conductivity and Salinity use TDR method, and uploads these values via wireless toNB-IoT Server. It is designed for outdoor use and powered by solar panel + 3000mAh Li-ion battery for long term use.

NPK-7in1 NB-IoT supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

NPK-7in1-NB supports BLE configure and OTA update which make user easy to use.

NPK-7in1 is powered by solar panel + 3000mAh Li-ion battery, it is designed for long term use up to several years.
