Alcohol detection alerts through EzloPi meshbot

The EzloPi smart devices provide automation through simple, customizable use with our open-source EzloPi platform, making daily life easier and improving human-machine interactions.

Before moving into this example, it is very important to know about the device registration, provisioning and converting the ESP32 device into an EzloPi device along with knowledge of Web Flasher, MiOS Mobile Application for Android/iOS and the MiOS Web Application.

The project aims to integrate an MQ3 alcohol sensor with the EzloPi device, utilizing its automation capabilities to create a robust alcohol detection system. The EzloPi automation meshbots will be employed to promptly alert the user when alcohol presence is detected in the surrounding atmosphere.

The MQ3 Alcohol sensor is a gas sensor widely used to detect the presence of alcohol vapor in the environment. It is particularly popular for applications involving alcohol detectors in automobiles, breath analyzers, and in various industrial safety systems. We can set up threshold values to trigger alerts or actions when alcohol concentration exceeds a certain limit. This could include sending notifications, activating alarms, or interfacing with other devices for safety measures and monitoring.

The following components are required for interfacing with the EzloPi device:

• ESP32 as an EzloPi smart device.
• MQ3 Alcohol sensor module.

The wiring diagram for the ESP32 30 pin is represented as below:

The following connections are made in order to complete the circuit setup:

From ESP32 to the MQ3 Alcohol Sensor:

• Connect Vin from the ESP32 to the VCC of the sensor.
• Connect GND from the ESP32 to the GND pin of the sensor.
• Connect D33 from the ESP32 to the A0 Pin of the sensor.

1. Set up your device/hardware by visiting config.ezlopi.com

2. Log in using the credentials which you just set earlier while signing up.

3. Now, click on the Connect Device button and a pop-up window will appear.

4. Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.

Click Connect.

5. If you are new to this and it's your first time configuring, select Create new Device ID. Enter Wifi SSID and Wifi Password.
6. In the Device Configuration, tab click on Other.

7. A window will open for inputting the following parameters:

• Set a device name of your choosing. In our case, we set it to MQ3.
• Set Device subtype to MQ3 Alcohol Sensor.
• Check the box of GPIO 1.
• Set GPIO 1 to 25.
• Check the box of GPIO 2.
• Set GPIO2 to 33.
• Then Click Apply Button.
• After clicking the apply button you can see a table of your setting in the device configuration tab.
• Press the Flash Device button.

8. A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”

9. Hold the BOOT button down until the next window appears on the bottom right side of the screen which says “Installation prepared. Please release the boot button now.”

10. Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.

11. After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.

1. After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com

2. Use the same credential to log in that you used for configuring the controller with the web flasher.

3. After opening the MiOS web dashboard, you see the tile of your connected device. The MQ3 Alcohol sensor tile will reflect the concentration readings of the alcohol vapors in the environment. As shown above, there is no gas being currently detected by the sensor.

Meshbots

4. On the right side of the screen under Automation, click on MeshBots.

5. On meshbot screen, click on Create new MeshBot button present on the top right corner of the screen.
6. After clicking on Create new MeshBot you will see this now under Automation MeshBot click on Cloud.

7. On the next screen you will see that we can create a name of our choosing, in this case we write it as MQ3.

8. In the trigger tab you can set the TRIGGER for your device and in the ACTION tab you can set the action to be performed based on the trigger which you have created.

9. Set these things in TRIGGER section:

• Set Node Type to Device.
• Set the Node to MQ3.
• Set the Capability to parent_abstract.
• Set the variables to uuid.
• Set the Comparator to Greater (>).
• Set the Value Type to value.
• Set the value to 10 (It will trigger when temperature is greater than 10).

10. Set these values in the ACTION section.

• Set Controllable Type to Notification.
• Set the User to Your user account but in our case the user account is Tayyab..
• Set the Channels to email,push.
• Set the Subject to Alcohol Detection Alert.
• Set the Message body info to Alcohol is Detected.
• After clicking the apply button you can see a table of your setting in the Current configuration tab.

11. After clicking the save button you can see this screen on the top right corner of the screen.

12. Here you can see your saved MeshBot. Now click on Dashboard.

13. The MQ3 Alcohol sensor tile reflects the concentration readings of the alcohol vapors being detected by the sensor at that moment i.e. greater than 10, therefore an email is sent to the user to alert about the detected alcohol vapor levels.

You can download the MIOS Android app from the Google Play Store and Apple App Store.

1. After downloading the app, proceed to install the application and open it.

2. Using the MIOS mobile application, create a new Ezlo Cloud account using the sign-up option. If you already have an account, you may proceed to log in.

3. After successfully logging in, you will be able to see the number of controllers connected such as a lamp, fan, or any other device in the MiOS app. Tap on any controller of your desired ID:

4. You will be able to see the status of your controller whether it is online or offline. Access the device dashboard, and tap the device. The following view of the dashboard will appear:

5. After opening the MiOS mobile dashboard, you will be able to see the tile of your connected device. The MQ3 Alcohol sensor tile reflects the concentration readings of the alcohol vapors being detected by the sensor at that moment.

6. The MQ3 Alcohol sensor tile reflects the concentration readings of the alcohol vapors being detected by the sensor at that moment i.e. greater than 10, therefore an email is sent to the user to alert about the detected alcohol vapor levels.
