Soil moisture transmitters are widely used in soil and water conservation monitoring, soil hydrology monitoring, fine agricultural production, precision irrigation and other fields. Soil moisture transmitter can measure the volumetric water content of soil in the surrounding 200cm capacity range. Soil moisture transmitter is characterized by high protection, high precision, small size, light weight, easy installation, lightning protection, anti-interference and so on. Today I would like to share with you how to troubleshoot and solve the soil moisture transmitter: First, the soil moisture transmitter does not measure the medium, the corresponding output value is not correct. Failure causes: soil moisture transmitter is not working in its required environment to use. Solution: Move the soil moisture transmitter to the required environment or take measures to make the environment meet the requirements. Second, soil moisture transmitter no output signal. Fault cause: soil moisture transmitter is not powered or soil moisture transmitter wiring error. Solution: Supply power to the soil moisture transmitter according to the wiring diagram. Third, the output of soil moisture transmitter jumps irregularly when the moisture is constant. Fault cause: 1, soil moisture transmitter is not grounded. 2、 Strong RF interference at the site. 3, soil moisture transmitter does not use shielded cable. Solution: 1, soil moisture transmitter need to use shielded cable and shielding layer grounding. 2、Soil moisture transmitter and earth reliable connection. Fourth, the soil moisture transmitter output does not match the measurement. Fault cause: soil moisture transmitter supply voltage is not correct or soil moisture transmitter external load is too large. Solution: 1, whether the soil moisture transmitter meets the power supply range 2, adjust the external load of the soil moisture transmitter.
