Soil Moisture Detection Humidity Sensor Module

Description

Smart Electronics Soil Moisture Hygrometer Detection Humidity Sensor Module For Arduino Development Board Description: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.Adjustable sensitivity ( shown in blue digital potentiometer adjustment ).Operating Voltage 3.3V-5V.Module Dual Output mode , a simple digital output , analog output more accurate.With fixed bolt hole for easy installation.Small PCB board size: 3cm * 1.6cm.Power indicator ( red ) and the digital switch output indicator ( green ).Using LM393 comparator chip, stable.VCC external 3.3V-5VGND GND ExternalDO 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
