Overview
This module detects flame fire, its sensitivity can be adjusted through variable resistor. Comparator using high accuracy and fast response LM393.
Features
- Operating voltage : DC +3.3V/5V
- Onboard power status LED : Lit when power is supplied.
- Onboard sensor status LED : Lit when not detected, turn-off when flame detected.
- Sensitive to IR wavelength at 760nm ~ 1100 nm light.
