How It Works
The Heat Flame Sensor uses a specialized infrared (IR) photodiode tuned to the 760nm-1100nm wavelength range - the spectrum where open flames emit strong infrared radiation. When a flame is present within the sensor's detection cone, the IR photodiode registers increased infrared energy. This signal is processed by the onboard LM393 comparator, which compares it against a threshold set via the potentiometer. If the signal exceeds the threshold, the digital output pin goes LOW (active), signaling flame detection. Simultaneously, the analog output provides a proportional voltage reading that reflects flame intensity and distance, allowing for more granular monitoring and data logging.
Pin Configuration
| Pin | Label | Description |
| 1 | VCC | Power supply input (3.3V-5V DC) |
| 2 | GND | Ground connection |
| 3 | DO | Digital output - LOW when flame detected, HIGH when no flame |
| 4 | AO | Analog output - voltage proportional to flame intensity |
