Maker Soil Moisture Sensor (Capacitive)

Description

Maker Soil Moisture Sensor measures soil moisture by capacitive sensing, where the presence of water in the soil will increase the probe capacitance. The output of the sensor is analog output; higher moisture levels will produce a lower output voltage. Being part of the Maker Series, the sensor is equipped with many features to further simplify digital making for beginners and experts alike.

Features

• Operating Voltage: 2.5V – 7.0V.
• Grove port.
• Output: Analog Voltage (Higher moisture = lower voltage)
• LED indicators for dry/moist/wet soil moisture levels.
• Soil Limit (Maximum depth of the probe)
• Double-sided probe (More sensitive to moisture changes)
• Capacitive sensing probe (Corrosion resistant)
• Disable pin (Power-saving application)

Example applications:

• Soil moisture detection
• Automatic Plant watering system
• Smart/IoT Gardens
