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.
Corrosion-Resistant Alloy Probe
A waterproof sensor probe with high corrosion resistance ensures a long lifetime at least 6 months in the soil.. Featured By RoboticsBD.
The soil humidity probe is for detecting humidity, and the voltage comparator is for judging humidity amount; when the humidity is larger than set value , DO will output low level.

Wiring Diagram 1:
When the detected value is more than the set value, DO will output low level, the triode will be connected and the load will operate. 1K is current-limiting resistor, and 10K is pull-up resistor on DO port.
Wiring Diagram 2:
No more complex circuits, AO port can collect voltage via MCU AD port.
