This is a new type of analog capacitive soil moisture sensor designed by DFRobot. Compared with the old soil moisture sensor, it has increased waterproof performance. Even if the sensor is fully immersed in water, it can still be used normally; the anti-corrosion performance is optimized and with the improved laminate design, you no longer need to worry about the soil scratching the sensor panel, resulting in accelerated corrosion of the sensor; the length of the electrode plate is increased and the circuit performance is optimized, the measurement range is expanded, and the measurement value of the sensor is more accurate!
In addition, the sensor still retains the built-in voltage regulator chip and supports a 3.3~5.5V wide voltage working environment, which means that 3.3V main control boards such as micro:bit, ESP32 and STM8/32 main control boards, etc can be used normally. On a mini PC like the Raspberry Pi, you only need an external ADC for it to work properly.
