RS485 4-in-1 EC-pH-Temperature and Soil Moisture Sensor IP68 5-30V

With the RS485 4-in-1 soil moisture, temperature, EC, and pH sensor, you can precisely monitor the most important parameters of your soil. This sensor offers a comprehensive solution for measuring soil moisture, temperature, electrical conductivity (EC), and pH level, ensuring optimal conditions for plant growth. It supports a wide input voltage of 5-30V and transmits data via RS485 with the reliable MODBUS-RTU protocol. The sensor is characterized by a fast response time and stable output, and it is compatible with Arduino UNO R3. Thanks to the IP68 protection class, the sensor is robust against water and dust and can remain permanently in the ground. The probe is made of stainless 316 steel, making it resistant to corrosion and long-term electrolysis. With automatic temperature compensation, the measurements remain accurate even in changing environmental conditions.
