Package Includes:

1X Soil Moisture Sensor

Note:

Instructions for use:

1.A soil moisture and moisture modulus most sensitive to the environment, usually used to detect soil moisture.

2.Modules in the soil moisture reach the set threshold, TUN port output high, when soil moisture reaches a set threshold, the module D0 output low;

3.Digital outputs D0 small plates can be directly connected to the microcontroller through the microcontroller detect high and low, reducing soil moisture;

4.Small plates digital output DO OUR relay module can directly drive the module, which can get out of a soil moisture alarm equipment;

5.Small plates AO analog output modules can be connected and AD through the AD converter, you can get a more accurate value of soil moisture.
