1x Soil Moisture Sensor
1x Soil moisture detector module
1x Female to female 6p jumper wire
This is a simple water sensor, can be used to detect soil moisture. Module Output is high level when the soil moisture deficit,or output is low. Can be used in module plant waterer device, and the plants in your garden no need people to manage.
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 also can connect to relay module directly to drive buzzer module, which can form a soil moisture alarm equipment. Analog output AO can be connected through the AD converter or microcontroller analog port to get more precise values of soil moisture.
