Flame Sensor Using Bharat Pi Board AndOled Display

The flame detection system is a compact and efficient solution designed to detect fire hazards using a flame sensor, the Bharat Pi board, and an OLED display. This system leverages the digital output of the flame sensor to identify the presence of a flame in real time. When a flame is detected, the system displays an alert message on the OLED screen, making it highly useful for fire safety applications.

This setup is ideal for environments where early fire detection is critical, such as kitchens, laboratories, factories, and remote locations. It is cost-effective, energy-efficient, and simple to integrate into existing safety systems.

By using the Bharat Pi board as the central processor, this system offers reliable performance and can be customized further for specific requirements. The OLED display ensures clear and immediate visual feedback, enhancing the user experience.

Hardware Connections

1. Flame Sensor:
2. VCC → Connect to the 3.3V or 5V pin of the Bharat Pi board.
3. GND → Connect to the GND pin of the Bharat Pi board.
4. DO (Digital Output) → Connect to GPIO27 of the Bharat Pi board.
5. OLED Display:
6. VCC → Connect to the 3.3V pin of the Bharat Pi board.
7. GND → Connect to the GND pin of the Bharat Pi board.
8. SCL (Clock) → Connect to GPIO3 (I2C SCL pin).
9. SDA (Data) → Connect to GPIO2 (I2C SDA pin).

Diagram Description

1. The flame sensor detects the presence of a flame and sends a digital signal (LOW for flame detected, HIGH for no flame) to GPIO27.
2. The OLED display communicates with the Bharat Pi board over the I2C protocol using GPIO2 and GPIO3 for data exchange.
