Soil Moisture Sensor with Analog and Digital Output
€2.40
Tax included
Soil moisture sensor with both analog (AO) and digital (DO) outputs. The DO pin toggles based on a threshold set via the onboard potentiometer, while the AO pin provides a precise humidity reading. 3.3-5V compatible.
Soil moisture detection module featuring a dual-channel probe. It provides an analog output (AO) for precise humidity measurement and a digital output (DO) that switches based on an adjustable threshold.
Specifications
- Operating voltage: 3.3 V to 5 V
- Sensitivity adjustable via the onboard blue potentiometer
- LM393 comparator chip for stability
- Dual outputs: Analog (AO) and Digital (DO)
- LED indicators: Power (red) and Output status (green)
- PCB dimensions: 3 x 1.5 cm
- Probe dimensions: 6 x 2 cm
