Description
The 5V Flame Sensor with Relay Module is a fire-detection device designed to sense flame and light sources within the 760–1100 nm wavelength range. Equipped with a high-sensitivity infrared sensor and onboard relay output, it can directly control high-current loads (AC 220V / DC 30V), making it suitable for fire alarm systems, safety devices, and automated fire-response projects. Its adjustable sensitivity and wide detection angle make it a versatile choice for home, lab, and industrial applications.
Key Features
- Flame Detection Range: Detects lighter flames at up to 80 cm (longer for larger flames).
- Wide Spectral Sensitivity: 760 nm ~ 1100 nm flame spectrum detection.
- Adjustable Sensitivity: Onboard blue potentiometer for fine-tuning.
- Wide Detection Angle: ~60° for improved flame recognition.
- Relay Control: Comparator output directly drives the relay for switching high-current equipment.
- Convenient Design: Blue terminal block for easy wiring + mounting holes for installation.
