*GitHub https://github.com/rdiot/rdiot-s022.git


* Specs

1 This is a summary of the 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, the digital output is simple, analog output is more accurate.

6 with fixed bolt hole for easy installation

7 small PCB board size: 3cm * 1.6cm

 

Small plate interface specification (4-wire)

1 VCC 3.3V-5V external

2 GND GND External

3 DO small board digital output interface (0 and 1)

4 AO small plates analog output interface

- Key Code

int sensorValue = analogRead(pin);

sensorValue = constrain(sensorValue, 485, 1023);


int soil = map(sensorValue, 485, 1023, 100, 0);


lcd.print("sensorValue=" + (String)sensorValue);
