Flame Sensor Module 5 Channel

From the shop's description

5 Independent Flame Sensors Use this module to detect flame over broad range ( >120 degree). It recognizes the fire using five independent sensors arranged with 30 degrees of separation. The module outputs both an analog signal (value varies with the intensity of sensed flame) and also a digital signal well suited to microcomputer applications. The onboard potentiometer can adjust the digital output sensitivity level. The 5 built-in LED indicators will assist in debugging and testing of the system. Mounting for the sensor board is by three M3 mounting holes for easy installation. Working Principle Detects flame band in the range of 700-1100 nm, short-wave near-infrared (SW-NIR) and triggers an output via an electric signal when sensed. Connection Pinout Features: 5-channel infrared flame sensor Detects fire/light at multiple angles High sensitivity to flame wavelengths Supports 3.3V–5V input Compatible with Arduino, ESP8266, ESP32, Raspberry Pi Ideal for firefighting robots, safety systems, and automation Adjustable sensitivity via onboard potentiometers
