Soil Moisture Sensor

Overview

      This sensor can be used to test the moisture of soil, when the soil is having water shortage, the module output is at high level, else the output is at  low level. By using this sensor one can automatically water the flower plant, or any other plants requiring automatic watering technique

Soil Moisture Sensor

Features:

• Sensitivity adjustable (shown in blue digital potentiometer control)
• Working voltage of 3.3 v - 5 v
• Module triple output mode, digital output is simple, analog output more accurate, serial output with exact readings.
• Has fixed bolt hole, convenient installation.
• Threshold level can be configured as shown in figure.
