Capacitive Soil Moisture Sensor with Buzzer
- Plant Watering Alarm Alerter Humidity Moisture Sensor Module – Soil Sensor Module
- Independent soil moisture sensor with built-in buzzer that gives a warning when the humidity is low.
- The sensor distinguishes itself from other soil moisture sensors by the capacitive measurement instead of a resistance measurement. This makes the sensor a lot more corrosion resistant and therefore lasts longer.

- Size: 140x15mm
