Why choose it

The sen-Moisture sensor offers a simple and reliable way to measure soil moisture. Its dual output modes give you flexibility: use the analog output for precise moisture level readings or the digital output with adjustable threshold for simple dry/wet detection. The onboard potentiometer lets you set the trigger point for the digital output, making it easy to integrate into automatic watering systems. The sensor's wide voltage range (3.3V–5V) ensures compatibility with most development boards.

Ideal use cases

• Automatic plant watering systems
• Soil moisture monitoring for gardens and greenhouses
• Educational projects with Raspberry Pi, micro:bit, or Calliope mini
• DIY smart home plant care
• Agricultural sensor prototypes

Good to know

The sensor uses a resistive measurement method: the probe's resistance changes with soil moisture content. The included LM393 comparator chip provides a clean digital signal. Note that the probe is not intended for continuous immersion in water; it is designed for periodic soil moisture checks. The kit includes one sensor module.
