This is a simple moisture sensor that can be used to detect soil moisture. When the soil is short of water, the module outputs a high level and vice versa. Use this sensor to create an automatic watering device that allows plants in your garden to be left unmanaged.
Sensitivity is adjustable (blue digital potentiometer adjustment in the figure)
The module has dual output mode, the digital output is simple, and the analog output is more accurate.
Fixed bolt holes for easy installation
Power indicator (red) and digital switch output indicator (green)
