Safety First: ESP32 LPG Leak Alarm with Remote Notifications
Description:
Learn how to detect gas leaks in real-time with this innovative DIY project using the Wemos D1 Mini board! In this tutorial, we'll show you how to build a gas leak detection system that can alert you to potential dangers in your home or office. Using a combination of MQ-5 sensor and the Wemos D1 Mini's Wi-Fi capabilities, you'll be able to monitor gas levels remotely and receive notifications in case of a leak. This project is perfect for DIY enthusiasts, makers, and anyone looking to improve home safety. So, let's get started and build a gas leak detection system that can give you peace of mind!
In this video, we’ll guide you through creating a DIY gas leakage detector using a Wemos D1 Mini, an MQ-5 gas sensor, an OLED screen, and a buzzer. This smart detector also includes real-time notifications through Pushover, so you can receive instant alerts on your smartphone when dangerous gas levels are detected!
Project Overview:
1. Wemos D1 Mini: This microcontroller will act as the central brain, connecting all the components and handling communication over Wi-Fi for sending alerts.
2. MQ-5 Gas Sensor: This sensor detects combustible gases like LPG, methane, and butane. When it detects a gas leak, it will trigger an alert.
3. OLED Display: The OLED screen will continuously display the gas levels, providing an at-a-glance status for easy monitoring.
4. Buzzer: For an immediate audio alert, the buzzer sounds off when gas levels exceed a set threshold, warning everyone nearby.
5. Pushover Notifications: With Pushover integration, you’ll receive instant notifications on your mobile device, keeping you informed of any gas leaks, even if you’re away.
What You’ll Learn:
Wiring the Wemos D1 Mini with the MQ-5 gas sensor, OLED screen, and buzzer.
Coding the logic to monitor gas levels, trigger the buzzer, and send notifications.
Setting up Pushover to send real-time alerts to your phone over the internet.
Programming the Wemos D1 Mini using the Arduino IDE.
Step-by-Step Guide:
1. Connecting Components: We’ll go through the wiring for each component—MQ-5 to the analog pin (A0), OLED screen on D1 and D2, and buzzer on D4.
2. Programming in Arduino IDE: We’ll walk through coding the D1 Mini to read the MQ-5 sensor, update the OLED display, sound the buzzer, and send notifications.
3. Configuring Pushover: We’ll cover how to set up Pushover, hardcode your user and app keys, and program the Wemos to send notifications automatically.
