Soil moisture sensor

The sensor to determine the moisture level of the soil. It is powered with the voltage from 3.3 V to 5 V. It has digital and analog output, making it compatible with most of the commissioning modules including Raspberry PiandArduino. The device can be used, for example, for measuring the moisture content of the soil in the pot.

The device consists of threeparts: measuring probe, detector module and wires. The probe needs to be connected with the main module via wires and place them in the soil where moisture will be measured.

The sensor has a digital D0 output that indicates the exceeding of the set values, using the potentiometer, and analog A0 that helps to get the accurate moisture value.

The potentiometer sets the threshold above which the output D0 is changed from a high to a low status. The D0 pin can be connected directly to the microcontroller or the development kit, including Arduinoor, for example, with a buzzer module which will signal too low or too high humidity level.

The sensor has an analog A0 output, which must be connected to the pin of the A/D converter (analog input inArduino). This will allow you to determine the humidity level more accurately while measuring the proportional voltage signal.
