YL-69 Soil Hygrometer Humidity & Soil Moisture Detection Sensor For Arduino

YL-69 Soil Hygrometer Humidity Detection Module Soil MoistureWater 

Sensor For Arduino

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.

Features:

• Brand new and high quality
• This is a simple water sensor, which can be used to detect soil moisture
