Description :

-This is a new type of analog capacitive soil moisture sensor designed by DFRobot with 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 more Laminate design, no longer need to worry about the sensors in 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!
-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 control, micro:bit, ESP32, STM8/32 main control boards, etc. The sensor can still be used normally. On a mini PC like the Raspberry Pi, you only need an external ADC to work properly.
