LM393 Soil Moisture Hygrometer Detection Humidity Sensor Module for arduino

3,000.00 2,500.00

  • VCC external 3.3V-5V

  • GND GND External

  • DO small board digital output interfaces ( 0 and 1 )
  • AO small board analog output interface

  • A soil moisture and humidity module most sensitive to the environment , usually used to detect soil moisture .
  • Modules in the soil moisture reach the set threshold , DO port output high when soil moisture exceeds a set threshold, the module D0 output low ;
  • Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ;
  • Small plates digital output DO OUR relay module can directly drive the buzzer module , which can be composed of a soil moisture alarm equipment ;
  • 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
