Frequently Asked Questions

What is the communication protocol and how do I wire this sensor?

The sensor uses the RS485 interface with the Modbus RTU protocol standard. It typically requires four wires: Power (VCC: 4.5-30V DC), Ground (GND), and the differential data lines (A+ and B-). You must connect these to an RS485 transceiver or a compatible data logger/PLC. Ensure proper termination and bias resistors are used on the bus for reliable long-distance communication.

Is this sensor suitable for permanent burial in the soil?

Yes, the probe is constructed from 316L stainless steel, which offers excellent corrosion resistance against most soil chemicals and moisture. This makes it ideal for long-term, permanent installation. For best practices, ensure the sensor is fully inserted into the soil at the representative depth for your monitoring needs and that the cable gland or connection point is properly sealed if exposed.

Can this sensor measure other parameters like moisture or temperature?

No, this specific SN-3000-TR-PH-N01 model is dedicated solely to soil pH measurement. The manufacturer offers other variants in the SN-3000 series for parameters like moisture, conductivity (EC), and temperature. If you require multi-parameter sensing, you would need to deploy individual sensors for each parameter or inquire about a combined multi-parameter probe assembly.

What is the required power supply and what is its power consumption?

The sensor operates on a wide DC voltage range of 4.5V to 30V, providing flexibility for use with battery packs, solar regulators, or standard industrial power supplies. Its power consumption is very low, with a working current of less than 20mA, making it highly suitable for remote, off-grid monitoring stations powered by solar panels and batteries.
