Soil Moisture Sensor, Icstation Humidity Detector, with Corrosion Resistant Probe, Digital Analog Signal Output for Arduino Raspberry Pi Garden Automatic Watering System (4Sets)

Specifications

Working Voltage: DC 3.3-12V

Working Current: <20mA (Output Current: <30mA)

Sensor Probe Length: 8.8cm/3.46 inch

Sensor Pin Pitch: 5 mm

Sensor Cable Length: 1.2 meters /3.94ft

Sensor Connecting Port: XH2.54 2P

DO Port: digital value output (DO output current is about 10mA)

AO Port: analog value outputDigital 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’ll be able to 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’s a LED power indicator at the P mark on the board. It’ll be light if the module operates most often.

2.Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. For instance, DO outputs low level when the moisture reaches 50% now, then I clockwise rotate the potentiometer to increase the detection threshold. At the moment, 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 the use of the DO output.

P

The probe uses analog resistance to detect the moisture content of the soil. This can be a good plant helper to make you know if your plants are thirsty and it may also be used in the automatic watering system, garden, greenhouse, and so forth.
