The utility model relates to the field of measurement technology and can be used to control the parameters of local land plots for various purposes for environmental, agricultural and other purposes. A soil moisture sensor is claimed containing a base in the form of a printed circuit board with a measuring element installed in it in the form of a moisture sensor. In this case, the data from the humidity sensor enters the signal processing circuitry located above the humidity sensor, which suppresses high-frequency interference from the humidity sensor data, converts the capacity of the humidity sensor to voltage for signal transmission to external devices through a four-pin connector located at the top of the base and connected to external devices that read the sensor readings and provide the setting of the sensor operating mode. Moreover, the part of the base on which the measuring element with the signal processing circuitry is located is covered with a sealed layer of waterproof electrical insulating varnish to protect it from aggressive influences. The technical result is an increase in the tightness of the device. 4 ill.
