ALLNET 4duino Flame Sensor (4duino_B05)

The ALLNET 4duino Flame Sensor (4duino_B05) is a high-sensitivity infrared flame detector module designed for use with Arduino, Raspberry Pi, ESP32, and other microcontrollers. It reliably detects flames in the 760nm to 1100nm wavelength range, making it ideal for fire detection and safety projects.

Advantages

Easy to integrate with both digital and analog outputs, adjustable sensitivity via onboard potentiometer, and fast response time of less than 10ms. The module includes power and status indicator LEDs for immediate visual feedback.

Suitable for

• Fire alarm systems
• Robot firefighting projects
• Safety monitoring applications
• Educational electronics kits
