Description:
- This is a simple water sensor that can be used to detect soil moisture when output a high level of soil and vice versa.
- We use this sensor to create an automatic plant waterler device. So you can control the plants in your garden without anyone
- Blue digital potentiometer adjustment (figure) with adjustable sensitivity
- Operating Voltage 3.3V-5V
- Module dual output mode, digital output, more accurate analog output.
- Easy installation with fixed bolt holes
- Power Indicator (red) and Digital Switching Output Indicator (green)
Specifications:
- Comparator LM393 chip, stable
- PCB size: about 3cm * 1.6cm
- Interface Description (4-wire)
- VCC: 3.3V-5V
- GND:GND
- DO: Digital output interface (0 and 1)
- AO: Analog output interface
- How to use:
- 1.Soil moisture module is most sensitive to ambient humidity, but is usually used to detect the amount of water in the soil.
- 2.Module D0 output is low, soil water, DO port output high setting threshold when soil humidity exceeds set threshold.
- 3. Digital output D0 can be connected directly with the microcontroller to detect high and low soil water by microcontroller.
- 4. Digital output DO store relay module can drive buzzer module which can form soil water alarm device.
- 5. Analog output AO and AD module connected via AD converter, you can get more accurate value of soil water.
