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.

Perfect for Arduino Projects

This sensor module worked flawlessly with my Arduino Uno. The sensitivity adjustment potentiometer is very responsive. Great for beginner robotics.

5 FAQ

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.
