Use this sensor to create an automatic plant watering device so that the plants in your garden do not need to be managed by humans. 2 Sensitivity adjustable (blue digital potentiometer adjustment in the figure) 4 Working voltage 3.3V-5V 5 modules double output mode, digital output is simple, analog output is more. 6 Bolt holes are provided for easy installation 7 PCB size: 3cm * 1.6cm 8 Power indicator (red) and digital switching output indicator (green) 9 The comparator uses LM393 chip and works stably

Two small board interface description (4-wire system) 1 VCC external 3.3V-5V 2 GND External GND 3 DO board digital output interface (0 and 1) 4 AO small board analog output interface Three instructions for use 1 Soil moisture module is sensitive to environmental humidity and is generally used to detect soil moisture. When the soil moisture does not reach the set threshold, the DO port outputs a high level; when the soil moisture exceeds the set threshold, the D0 module outputs a low level. 3 Small board digital output D0 can be directly connected with the MCU, through the MCU to detect high and low levels, thus detecting soil moisture; 4 Small board digital output DO can directly drive the relay module, buzzer module, etc., which can form a soil moisture alarm equipment; 5. The output AO of the small plate analog quantity can be connected with the AD module. Through the AD conversion, more values of soil moisture can be obtained;

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
