Distance measurement using Sonar sensor
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.
1. About this example
This project demonstrates interfacing the MB1013 sonar sensor module with the EzloPi device to enable distance measurement and environmental monitoring. The MB1013 sensor, known for its precision and reliability, uses ultrasonic waves to measure distances up to five meters. By connecting it to the EzloPi device, the data from the sensor can be processed and utilized for applications like object detection, obstacle avoidance, or level sensing.
2. Project Demonstration Video
Welcome to the project demonstration video section. The following video showcases the key aspects of Distance measurement using Sonar sensor, providing a visual walkthrough of its implementation.
3. Circuit Diagram & Interface
The following components are required for interfacing with the EzloPi device:
- ESP32 as an EzloPi smart device.
- MB1013 Sonar sensor module.
The wiring diagram is represented as follows:
The following connections are made in order to complete the circuit setup:
From ESP32 to the MB1013 module:
ESP32 | MB1013 |
3V3 | VCC |
GND | GND |
D16 (RX) | Tx |
D17 (TX) | Rx |
4. Interfacing the MB1013 Sonar sensor module using the EzloPi Web Flasher
1. Set up your device/hardware by visiting config.ezlopi.com
- Log in using the credentials which you just set earlier while signing up.
- Now, click on the Connect Device button and a pop-up window will appear.
Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.
Click Connect.
- If you are new to this and it's your first time configuring, select Create new Device ID. Enter Wifi SSID and Wifi Password.
- In the Device Configuration, tab click on Digital Input.
- A window will open for inputting the following parameters:
- Set a device name of your choosing. In our case, we set it to Sonar Sensor.
- Set Device subtype to MB1013.
- Set GPIO RX to 16.
- Set GPIO TX to 17.
- Set Baud Rate to 9600.
- 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.
- A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”
- 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.”
- Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.
- After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.
5. MiOS App
You can download the MIOS Android app from the Google Play Store and Apple App Store.
- After downloading the app, proceed to install the application and open it.
- 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.
- 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:
- 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:
- After opening the MiOS mobile dashboard, you will be able to see the tile of your connected device. Now the dashboard tile is displaying the distance to the object detected by the sensor as seen above.
6. MiOS Web Application
- After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com
- Use the same credentials to log in that you used for configuring the controller with the web flasher.
- After opening the MiOS web dashboard, you will be able to see the tile of your connected device. Now the dashboard tile is displaying the distance to the object detected by the sensor as seen above.
