Soil Moisture Sensor Soil Hygrometer Humidity Detection Module

Soil Moisture Sensor Module is used to accurately measure the moisture in the substrate (Moisture Sensor), which gives you the opportunity to give your plants the best care.

Features:

• 2 soil probes for detecting soil moisture
• Operating voltage of 5V
• Digital output D0 for direct connection to microcontroller
• Analog output A0 for more accurate values
• Adjustable switching contact with potentiometer

Pin Out:

• VCC: For power
• A0: Analog output
• D0: Digital output
• GND: Ground

This Module also contains a potentiometer which will set the threshold value and then this threshold value will be compared by the LM393 comparator. The output LED will light up and down according to this threshold value. The working voltage of 3.3 V to 5 V.

• Simple digital output, g v directly by single chip microcomputer
• Sensitivity is adjustable using digital potentiometer (blue)
• Fixed bolt hole for convenient installation
• Power indicator light (red) and digital switch output indicator light (green)
• Comparator uses the LM393 chips for stable work
