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

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.

Upload the Code
Below is an example code.

What You Should See
When detect the different degree of humidity, the sensor outputs different value. If the sensor’s sensing area detects a water drop, the analog value will be displayed on monitor window.

Extension Experiment
Adding LCD Display
Hookup Guide
Connect the EASY Plug steam sensor and LCD module to control board using RJ11 cables.

Test Code
Below is an example code.

What You Should See

Upload the code successfully, if the sensor detects a drop of water, the data will be showed on the LCD screen.

Little Knowledge:

• Remember you can adjust the contrast by rotating a blue potentiometer on the LCD back if you can’t make out the words clearly.
