Moisture Sensor 土壤濕度感測器
通過電位器調節土壤濕度控制閥值,可以自動對菜園,花園自動澆水,家庭花盆土壤濕度的控制,各種電子比賽,電子積木,arduino設計等。
產品介紹:
1.採用本公司生產的優質土壤傳感器做土壤濕度的檢測,表面採用鍍鎳處理,有加寬的感應面積,可以提高導電性能,防止接觸土壤容易生鏽的問題,延長使用壽命
2.產品可以寬範圍控制土壤的濕度,通過電位器調節控制相應閥值,濕度低於設定值時,DO輸出高電平,高於設定值時,DO輸出低電平;
3.比較器採用LM393芯片,工作穩定
4.工作電壓3.3V-5V
5.設有固定螺栓孔,方便安裝
6.PCB尺寸:3.2cm * 1.4m
接線說明(3線製)
1 VCC外接3.3V-5V
2 GND外接GND
3 DO小板數字量輸出接口(0和1)
模塊使用說明:
1.傳感器適用於土壤的濕度檢測;
2.模塊中藍色的電位器是用於土壤濕度的閥值調節,順時針調節,控制的濕度會越大,逆時針越小;
3.數字量輸出D0可以與單片機直接相連,通過單片機來檢測高低電平,由此來檢測土壤濕度;

void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
Soil Moisture Meter Testing Module, Soil Humidity Sensor
Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
Module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceeds the threshold value is set, the module D0 output low;
Small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and thus to detect soil moisture;
Small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisture alarm equipment;
Small plates analog output AO and AD module connected through the AD converter, you can get more accurate values of soil moisture;
