Soil Moisture Meter Detection Module(pack of 10)
Features:
This is a simple moisture sensor that can be used to detect soil moisture. 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.
Sensitivity is adjustable (the blue digital potentiometer is adjusted in the picture).
Module dual output mode, digital output is simple, analog output is more accurate.
Equipped with fixing bolt holes for easy installation.
Small board PCB size: 3cm * 1.6cm.
Power indicator (red) and digital switch output indicator (green).
The comparator uses the LM393 chip, which works stably.
Two small board interface specifications (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
Instructions for use
The 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 high level. When the soil moisture exceeds the set threshold, module D0 outputs low level.
The small-board digital output D0 can be directly connected to the single-chip microcomputer, and the high and low levels can be detected by the single-chip microcomputer, thereby detecting the soil moisture.
The small-board digital output DO can directly drive our relay module, buzzer module, etc., which can form a soil moisture alarm device.
The small board analog output AO can be connected to the AD module, and through AD conversion, a more accurate value of soil moisture can be obtained.
A set of finished boards of soil moisture detection module (including detection board and soil moisture probe)
Package Including:
10*Moisture Meter Detection Module
