Grove - Water Atomization

Introduction

5.0V Digital

Grove - Water Atomization is a fine Grove module for you to develop an atomizer or an atomizer module in your applications easily. With a few simple steps, you can prototype an atomizer. It has grove interface which make it easily applied to plenty of applications. A humidifier is a basic application it can be built with, you can develop more advanced and interesting objects with digital scent technology and any other situation in which atomization is required.

Features

  • Heated with ultrasound.
  • Easy to prototype a new application.
  • Well applied to vast applications.
  • For various interesting, smart and fashionable applications.

Tip

More details about Grove modules please refer to Grove System

Application ideas

  • Humidifier.
  • Scent emitter in different situations.
  • For smart-house applications.
  • For smart objects on consumer electronic products.

Get started

Material required

Seeeduino v4.2 x 1

Grove - Base shield v2 x 1

Grove - Wire x 1

Preparations

Refer to following guides to build an appropriate IDE:

Note

We have chosen Seeeduino in this case.

Getting Started on Windows

Getting Started on Mac OS X

Hardware connections

A little demo

Note

We also need a Grove - Touch Sensor in this demo and also connect it to A5(Use as digital pin).

1.Copy code below to Arduino IDE editor.

/*
  Demo code for grove  atomization.
  Touch to start atomizing.

// the setup function runs once when you press reset or power the board
void setup() {
    // initialize digital pin 13 as an output.
    pinMode(A5, OUTPUT);// Set A5 as OUTPUT
    pinMode(5, INPUT); // Use digital pin 5 as output port
}

// the loop function runs over and over again forever
void loop() {
    int D2Sig = digitalRead(5);// read pin 5 signal
    if (D2Sig == 1)
    {
        /* code */
        digitalWrite(A5, HIGH);   // atomize
        delay(10000);              // wait for 10 seconds
        digitalWrite(A5, LOW);    // atomization stopped

    }
}

2.Place some tissue into a trimmed paper cup filled with water, put ultrasonic transducer onto tissue.

Note

The bottom side is the side with hollow which is supposed to face downside. Let bottom of transducer plate sink into the water and keep top side above water. The function of tissue is lead water to the transducer and keep upper side of transducer above water.

3.Upload code to main control board.

4.Now if you touch Grove touch sensor, you can see vapor produced.

Caution

Do not touch transducer interface pins directly because peak output voltage of Drier board can be 65V.

Caution

The inductor L2 (marked in red rectangle above) will be heated. So do not touch it directly.

Caution

The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
