This moisture sensor changes the output voltage with different level of humidity. It is commonly used to detect humidity of soil. By using this sensor to determine the humidity of the soil, you can create your own "self-watering plant" system.

Specification:
Current Consumption: < 20mA
Input Voltage: 3.3V, 5V
Output voltage: 5V maximum voltage
or between 0-3.6V (of which 3.6V voltage is completely immersed in water)
Dimension: 60 x 20mm
Weight: 4g

Application: Self watering plant system

Note: different water quality might produce some variation in the output voltage. This sensor is also a consumable item, it has an expected life of 1 year in service.
