5x Floor Moisture Hygrometer Moisture Detection Water Sensor Module Arduino Cabl
This is a simple water sensor that can be used to detect soil moisture. Can be used in module plant waterer device, and the plants in your garden no need people to manage. This is a must have tool for a connected garden! It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. Operating voltage: 3.3V-5V Module dual output mode, digital output, analog output more accurate.
Interface Description (4-wire):
DO: digital output interface (0 and 1)
AO: analog output interface
Instructions for Use:
Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
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.
