Description 1 This is a simple moisture sensor that can be used to detect the moisture in the soil. When the soil lacks water, the module outputs a high level, otherwise it outputs a low level. Use this sensor to make an automatic watering device, so that the plants in your garden do not need to be managed by humans. 2 Sensitivity is adjustable (the blue digital potentiometer is adjusted in the picture) 4 Working voltage 3.3V-5V 5 Module dual output mode, simple digital output, more accurate analog output. 6 Equipped with fixing bolt holes for easy installation 7 Small board PCB size: 3cm * 1.6cm 8 Power indicator (red) and digital switch output indicator (green) 9 The comparator uses the LM393 chip, which works stably Two small board interface description (4-wire system) 1 VCC external 3.3V-5V 2 GND External GND 3 DO small board digital output interface (0 and 1) 4 AO small board analog output interface Three instructions 1 The soil moisture module is sensitive to environmental humidity and is generally used to detect soil moisture. 2 When the soil moisture does not reach the set threshold, the DO port outputs high level. When the soil moisture exceeds the set threshold, module D0 outputs low level; 3 The small-board digital output D0 can be directly connected to the single-chip microcomputer, and the high and low levels are detected by the single-chip microcomputer, thereby detecting the soil moisture; 4 small board digital output DO can directly drive our relay module, buzzer module, etc., which can form a soil moisture alarm device; 5 The analog output AO of the small board can be connected with the AD module, through AD conversion, a more accurate value of soil moisture can be obtained
