FC-28 Soil Moisture Module YL-69

:Product descriptionhigh-quality soil sensors to detect soil moistureyou can control a wide range of soil moisture, the corresponding threshold adjustment control by potentiometerhumidity is below the set value, DO output highhigher than the set value, DO output lowusing LM393 comparator chip, stableOperating Voltage 3.3V-5Vwith fixed bolt hole for easy installationPCB Size: 3.2cm * 1.4m(Wiring (4-wireVCC external 3.3V-5VGND GND External(DO small board digital output interfaces (0 and 1AO analog output voltage of small plates :Note for usesensor for detecting moisture in the soilmodule is the blue potentiometer to adjust the threshold for soil moisture, clockwise adjustment, control humidity, the smaller counterclockwisedigital outputs D0 can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting soil moisturesmall plates AO analog output modules can be connected and AD through the AD converter, you can get a more accurate value of soil moisture
