MD0504 Soil Moisture Sensor Module Soil DC 3.3V-12V Corrosion Resistance Detector Probe for Soil Moisture Hygrometer Tester

Product Specifications:

Product Name: Soil Moisture Sensor

Size: 36×15×7mm

Voltage: 3.3 -12VDC

Current:

Working <20mA

Output <30mA

Interface: DO: digital, AO: analog

Wire Length: 1.2m

Notice:

1. [+] is connected to the positive pole of the power supply, [-] is connected to the negative pole of the power supply. Please do not reverse the connection. It is responsible for burning the chip. After the power is connected, the [P] power indicator lights up and the module works normally.

2. The blue potentiometer adjusts clockwise/counterclockwise to increase/decrease the probe detection sensitivity. Take the "thermal sensor" as an example, assuming the default is 25 degree trigger, [DO] output is active low. Clockwise adjustment , the temperature can be triggered below 25 degrees. Counterclockwise is higher than 25 degrees trigger.

3. It indicates that the adjustment range has exceeded the test threshold when the potentiometer is adjusted clockwise until the [S] output indicator is on. The threshold value is exceeded when the counterclockwise adjustment is unable to adjust. The threshold cannot be exceeded when adjusting, otherwise it cannot be used.

4. [AO] output is analog (voltage), which can be directly detected by the AD port of the MCU.
