EASY PLUG Super Starter Kit For Arduino Project 16: How to detect the water drop?

Posted by Fiona Su on

Overview
This experiment we are going to detect the water drop using keyestudio EASY Plug steam sensor. It is an analog sensor that can be used to make simple rain detectors and level switches.
Component Required

  • EASY plug control board*1
  • EASY plug Steam Sensor *1
  • EASY plug 1602 LCD Module *1
  • RJ11 cable*1
  • USB cable*1

Component Introduction

Keyestudio EASY plug Steam Sensor
Vapor Sensor is an analog sensor and can make a simple rainwater detector and liquid level switch. When humidity on the surface of the sensor goes up, the output voltage will increase.
Warning: The connector is not waterproof, please be careful not to put the connector directly in water.
The module can be connected to the analog input interface with only one line, which is very easy and convenient.

  • Working Voltage: 5V
  • Working Current: <20mA
  • Working Temperature: -10℃~+70℃
  • Interface Type: Analog Signal Output

Connect It Up
Connect the EASY Plug Steam Sensor to control board using an RJ11 cable.
