Resistive Soil Moisture Sensor Digital Analog Signal Output for Arduino The probe uses analog resistance to detect the moisture content of the soil. It is a good plant helper to make you know if your plants are thirsty and it can also be used in the automatic watering system, garden, greenhouse, etc A waterproof sensor probe with high corrosion resistance ensures a long lifetime of at least 6 months in the soil. For those who are not sure how to use these, we would suggest looking into how to use these online. The voltage required, analog reading, etc. Digital Value Output This soil moisture detector outputs a low level from the DO port when the detecting humidity reaches the threshold value. Good to work with Arduino/Raspberry Pi. Analog Value Output The AO port on the soil humidity sensor outputs an analog value(voltage), and you can acquire the real-time data via the AD port of your single-chip microcomputer(MCU). Adjustable Threshold Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. On-board power and signal indicator make you know the working status of the board at a glance at any time. Instruction: 1."+" connects power positive; "-" goes to negative. Don't connect reversely or the chip will be burnt out. There is a LED power indicator at the P mark on the board. It will be light if the module operates normally. 2.Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. For example, DO outputs low level when the moisture reaches 50% now, then I clockwise rotate the potentiometer to increase the detection threshold. At this time, DO outputs a low level only when the moisture reaches a point higher than 50%. 3. If you clockwise rotate the potentiometer to an extent that the LED indicator which marked "S" is light, that means the testing threshold has been surpassed. Counterclockwise rotating to the end surpasses the threshold too. The module will not work well if the detection threshold is invalid. NOTE: The threshold adjustment only works for using the DO output.
