HiLetgo 5pcs LM393 3.3V-5V Soil Moisture Detect Sensor Soil Moisture Sensor Soil Hygrometer Detection for Arduino Automatic Watering System Robot Smart car

Description

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: 5LM393 Soil Moisture Sensor

Features:

• 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, stable job
