Through the potentiometer to adjust the soil moisture control threshold, can automatically on the garden, Garden automatic watering, home flowerpot soil moisture control, various electronic games, electronic building blocks, arduino design.
1. The use of the company’s production of high-quality soil sensors to do soil moisture detection, surface nickel-plated treatment, with a wider induction area, can improve electrical conductivity, prevent easy to contact soil rusting problem, extend service life; 2. The product can control the soil humidity in a wide range, and the corresponding threshold can be controlled by potentiometer. When the humidity is lower than the set value, the DO output is higher than the set value, the DO output is lower; 3. Comparator using LM393 chip, stable operation 4. Operating Voltage 3.3 v-5 V5. Fixed bolt hole for easy installation 6. Pcb Size: 3.2 cm * 1.4 m
1VCC external 3.3 V-5V2 GND external GND3 DO panel digital output interface (0 and 1)
1. The sensor is suitable for measuring soil moisture. 2. The Blue potentiometer in the module is used for the threshold regulation of soil moisture, clockwise regulation, the higher the controlled humidity, the lower the anticlockwise; 3. Digital output D0 can be directly connected with the single-chip microcomputer, through the single-chip microcomputer to detect high and low levels, thus to detect soil moisture
1. Modules and soil sensors a set of 2.20 cm long dupont line 2
