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
