Hygrometer Detection Soil Moisture r Sensing Module Soil Humidity r Module for Arduino Automatic Watering System

Descrtion:

This is a simple moisture r can be used to detect soil moisture, when the soil water, the r output of the og value will be reduced, and vice versa will increase. Use this r to make an automatic watering device. When you are not at home or after a long time, it can sense if your plant is already thirsty. To prevent the plants withered to know that is caused by water. With the Arduino controller to make your plant more comfortable, the garden is more intelligent. The r surface is metallized to extend its use of time. Insert it into the soil and then use the AD converter to read it. With its help, the plant will remind you: I want to drink water, please give me a little water to drink. Specification: Supply voltage: 3.3V or 5V Operating current: le than 20mA Output voltage :0-2.3 V [2.3V is completely immersed in water] voltage, 5V power supply, humidity, the greater the output voltage increases. r Type: og Output Interface Definition: DATA GND VCC Paage included: 1 x Hygrometer Detection Soil Moisture r Sensing Module Soil Humidity r Module for Arduino Automatic Watering System
