YL-69 Soil Hygrometer Humidity Detection Module Soil MoistureWater Sensor For Arduino
IN STOCK
Instructions for Use :
-
Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
-
Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value,
the module D0 output low.
-
The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture.
-
The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment.
-
Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
