Material

Description This is a set of the soil moisture sensor can be used to detect moisture, which is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. when the soil is dry, the module outputs a high level, whereas output low. Easy to install and use. Features - Color: As shown - Material: Metal and plastic - Size: 12x6x2cm - Operating voltage: 3.3V~5V. - Panel PCB Dimension: 3cm x 1.6cm. - Using this sensor make an automatic watering system to manage your garden plants without people. - Adjustable sensitivity (shown in blue digital potentiometer adjustment) - Dual output mode, more accurateanalog output. - A fixed bolt hole for easy installation. - With power indicator (red) and digital switching output indicator (green). - Adopt LM393 comparator chip for stable working. - Interface Description(4-wire): - VCC: 3.3V-5V. - GND: GND. - DO: digital output interface(0 and 1). - AO: analog output interface. Instructions for Use 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 2. Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low. 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture. 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment. 5.
