1Piece Humidity Hygrometer Moisture Detection Sensor Module for

Description: This is used to detect when the deficit module outputs a high level, and vice output Use this sensor produced an automatic plant waterer device, so that the plants in your garden without people to manage. Sensitivity adjustable the blue digital potentiometer adjustment (Figure) Operating voltage 3.3V-5V Module dual output mode, digital output, analog output more accurate. With hole for easy installation Power indicator switching output indicator Specification: Comparator LM393 chip, stable size: Approx. 3cm * 1.6cm/ 1.18x 0.63inch Interface Description (4-wire) VCC: 3.3 V-5V GND: GND DO: digital output interface (0 and 1) AO: Analog Output Interface Instructions for use: 1. module is most sensitive to the ambient humidity is generally used to detect the moisture content of the . 2. Module to reach value is set in the , DO port output high, when the the humidity exceeds a set threshold value, the module D0 output low; 3. The digital output D0 can be connected directly with the to detect by the to detect ; 4. The digital outputs relay module can directly drive the module, which can form moisture equipment; 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of ; Package Includes: 1 Piece module 1 Piece sensor 5 Pieces Lines
