description:
What it is a simple moisture sensor can be used to detect soil moisture, soil water when the module outputs a high level, whereas the output low. Using this sensor make an automatic watering system, so that your garden plants need people to manage.
2 adjustable sensitivity (shown in blue digital potentiometer adjustment)
4 Operating Voltage 3.3V-5V
5 module dual output mode, a simple digital output, analog output is more accurate.
6 has a fixed bolt hole for easy installation
7 small board PCB size: 3cm * 1.6cm
8 Power indicator (red) and digital switching output indicator (green)
9 comparators LM393 chip, stable

Two small plate interface specification (4-wire)
1 VCC 3.3V-5V external
2 GND External GND
3 DO small board digital output interface (0 and 1)
4 AO small plates analog output interface
Three instructions
1 soil moisture module for humidity most sensitive, generally used to detect soil moisture.
2 module in soil moisture reach the set threshold, DO port output high, when soil moisture exceeds the set threshold, the module D0 output low;
3 small board digital output D0 can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting soil moisture;
4 small board digital output DO OUR relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment;
5 small plates AO analog output module can be connected to AD, by the AD converter, you can get more precise values of soil moisture;
