โมดูลเซนเซอร์ตรวจจับความชื้นสําหรับ Soil Moisture Hygrometer Detection Humidity Sensor Module arduino

Soil Moisture Hygrometer Detection Humidity Sensor Module For arduino Development Board DIY Robot Smart Car

Description:
1 This is a summary of the moisture sensor can be used to detect the moisture of the soil when the soil is dry the module outputs a high level whereas the output low. Using this sensor make an automatic watering system so that your garden plants need people to manage .

2 adjustable sensitivity ( shown in blue digital potentiometer adjustment )

4 Operating Voltage 3.3V-5V

5 Module Dual Output mode a simple digital output analog output more accurate.

6 with fixed bolt hole for easy installation

7 small PCB board size : 3cm * 1.6cm

8 power indicator ( red ) and the digital switch output indicator ( green )

9 using LM393 comparator chip stable

VCC external 3.3V-5V
GND GND External
DO small board digital output interfaces ( 0 and 1 )
AO small board analog output interface

Instructions
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 ;

Package Included:
1pcs X Soli moisture sensors
