Great for Smart Cars
I used this for my smart car project to detect wet surfaces. It responds quickly to moisture changes. Highly recommend for hobbyists.

Sensitive and Reliable
Works well in soil testing. Just make sure to adjust the threshold correctly for your specific use case. Solid build quality.

Good Value for Money
Does exactly what it says. The only reason for 4 stars is that the headers were not pre-soldered, but that is standard for these modules.

Fast Shipping
Arrived earlier than expected. Packaging was secure. Tested it immediately and the LED indicators work well to show status.

Perfect for Arduino Projects
This sensor module worked flawlessly with my Arduino Uno. The sensitivity adjustment potentiometer is very responsive. Great for beginner robotics.
Q: Can this be submerged in water?
A: No, this is designed for soil moisture detection. Submerging the PCB entirely may damage the electronics.
Q: Does this output analog or digital signals?
A: This specific module outputs a digital switch signal (0 and 1). For analog readings, please check our analog soil moisture sensor listing.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the PCB. Turn it clockwise to increase sensitivity and counter-clockwise to decrease it.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, this module operates at 3.3V to 5V, making it fully compatible with Raspberry Pi GPIO pins.
Q: Are jumper wires included in the package?
A: The package includes the sensor module and a set of male-to-female jumper wires for easy connection.
