5pcs LM393 3.3V-5V Soil Moisture Detect Sensor Soil Moisture Sensor Soil Hygrometer Detection

Description

This is a simple moisture sensor can be used to detect soil moisture, when the soil water shortage, the module outputs a high level, whereas the output low.
Use this sensor to make an automatic watering device that will keep your garden of plants unmanaged.
Module dual output mode, digital output is simple, more accurate analog output.
Sensitivity adjustable (Figure blue digital potentiometer adjustment)
Comparator using LM393 chip.

Wiring ( 4 -wire )：
1）VCC external 3.3V-5V
2）GND External
3）DO small board digital output interfaces ( 0 and 1 )
4）AO analog output voltage of small plates

Instruction:
1. Sensor for detecting moisture in the soil
2. Sodule is the blue potentiometer to adjust the threshold for soil moisture , clockwise adjustment, control humidity will be bigger, smaller counter-clockwise
3. Digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture
4. Small plates AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture
5. Operating Voltage 3.3V-5V
6. Has a fixed bolt holes for easy installation
7. PCB Size : 3.2cm * 1.4m

Package Included:
5x LM393 Soil Moisture Sensor
