Soil Moisture Detection Humidity Sensor – Kuongshun Electronic Shop

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-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
