Delivery:

By adjusting the soil moisture control threshold via a potentiometer, this system enables automatic watering for vegetable gardens and flower beds, regulates soil moisture in household plant pots, and supports various electronic competitions, electronic building blocks, and Arduino designs.

【1】Employing our company’s soil sensor for moisture detection, featuring a nickel-plated surface with an enlarged sensing area. This enhances conductivity, mitigates rusting upon soil contact, and extends service life.
【2】The product enables wide-range soil moisture control via potentiometer-adjusted thresholds. When humidity falls below the set value, the DO output is high; when exceeding the set value, the DO output is low.
【3】The comparator utilises an LM393 chip for stable operation.
【4】Operating voltage: 3.3V–5V.
【5】Features mounting bolt holes for convenient installation.
【6】PCB dimensions: 3.2cm × 1.4cm.

3-wire system
1. VCC: External 3.3V–5V supply
2. GND: External ground connection
3. DO: Sub-board digital output interface (0 and 1)

【1】The sensor is suitable for detecting soil moisture levels;
【2】The blue potentiometer within the module adjusts the soil moisture threshold. Turning it clockwise increases the controlled humidity, while turning it anticlockwise decreases it;
【3】Digital output D0 can be directly connected to a microcontroller, which detects high and low logic levels to monitor soil moisture.
