This module detects the infrared light emitted by flames, making it useful for basic fire detection projects and alarms. It is typically used with a microcontroller via a simple digital and/or analog signal output, depending on the board version.
| Pin | Signal | Description |
|---|---|---|
A0 |
analog | Analog flame intensity output — connect to an MCU ADC input. |
GND |
ground | Ground reference for the module and connected microcontroller. |
VCC |
power | Positive supply input for the sensor module, typically 3.3V or 5V. |
D0 |
digital | Digital flame detect output from comparator, threshold set by onboard potentiometer. |
