==Overview==
This Moisture Sensor can detect the moisture of the soil around the sensor, which is ideal for monitoring the indoor plants or the soil moisture in your garden. It can be very to use, just insert it into the soil and then read it.

This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity better, while dry soil conducts electricity is poor.

==Specification==
*Power supply: 3.3v or 5v
*Output voltage signal: 0~4.2v
*Current: 35mA

*Value range:

0 ~300 : dry soil<br>
300~700 : humid soil<br>
700~950 : in water<br>
