0-3V 0-5V Rs485 Output Modbus Capacitive Water Level And Temperature 2 In 1 Sensor For Rice Fields
Product Vedio
Product Features
1. Test the liquid level value through the capacitance principle, the data can be accurate to mm, low cost, high accuracy, and can measure temperature at the same time
2. Applied in paddy field liquid level measurement, compared with ultrasonic level meter, it can be free from interference from paddy field leaves, and compared with hydraulic level meter, it can avoid probe blockage (scenario comparison)
3. Support analog output (0-3V, 0-5V), support digital output RS485 output MODBUS protocol
4. Low power consumption, can integrate battery version LORA/LORAWAN collector, work for a long time without battery replacement
5. Can integrate GPRS/4G/WIFI various wireless modules, as well as corresponding servers and software, can view data in real time on APP and computer
Product Applications
Application scenarios: rice field water level monitoring, smart agriculture, water conservancy irrigation
