Soil and Water Moisture Monitoring Station  

The soil and water moisture monitoring instrument is equipped with multiple intellectual property rights, including a pH sensor, salinity sensor, EC sensor, pressure water level sensor, and water temperature sensor. The instrument supports various IoT communication technologies such as GPRS, NB-IoT, and LoRa, and is powered by solar energy. It uploads detection data to the server every 10 minutes, with data permanently retained.  This instrument is suitable for monitoring and alarming pH and salinity in saline-alkali fields, as well as water level monitoring and alarming in irrigation areas. The device features high precision, retrievable historical data, and portability.  When salinity or pH exceeds the set range, the drainage valve automatically opens to drain the water from the field.  Once the water is drained, the drainage valve closes, and the inlet valve opens to execute the water-filling instruction until the water level reaches the set value, after which the inlet valve closes.
