Hw-330 Capacitive Soil Moisture Sensor Arduino Soil Moisture Sensor

Product details

This Capacitive Soil Moisture Sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor. Capacitive Soil moisture sensor is made of a corrosion-resistant material giving it long service life. Insert capacitive soil moisture sensor into the soil and impress your friends with the real-time soil moisture data!. The product includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required. Features Of Capacitive Soil Moisture Sensor: Operating Voltage: 3.3 ~ 5.5 VDC Output Voltage: 0 ~ 3.0VDC Interface: PH2.0-3P Dimension: 98mm * 23mm (3.86in x 0.905in) Supports Gravity 3-Pin interface Analog output Applications: Garden plants Moisture detection Intelligent agriculture Product Wiki /*************************************************** This example reads Capacitive Soil Moisture Sensor. ****************************************************/ const int AirValue = 520; //you need to replace this value with Value_1 const int WaterValue = 260; //you need to replace this value with Value_2 int intervals = (AirValue - WaterValue)/3; int soilMoistureValue = 0; void setup() { Serial.begin(9600); // open serial port, set the baud rate to 9600 bps } void loop() { soilMoistureValue = analogRead(A0); //put Sensor insert into soil if(soilMoistureValue > WaterValue && soilMoistureValue < (WaterValue + intervals)) { Serial.println("Very Wet"); } else if(soilMoistureValue > (WaterValue + intervals) && soilMoistureValue < (AirValue - intervals)) { Serial.println("Wet"); } else if(soilMoistureValue (AirValue - intervals)) { Serial.println("Dry"); } delay(100); }
