描述
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;

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;
