Infrared Obstacle Avoidance IR Sensor Module (Active Low)
Candle Safety
1. Trim your wick before burning your candle the first time and every subsequent burn thereafter.
2. We advise burning your candle for periods of no longer than three hours at a time.
3. Discontinue burning your candle when there is 10mm / 1cm of wax is remaining.
4. Always burn your candle on a stable and heat resistant surface, away from drafts or items that can catch alight.
5. Never leave a burning candle unattended, near children or pets.
6. If you’re burning more than one candle at a time, space your candles approximately 100mm (10cm) apart.
Infrared Obstacle Avoidance IR Sensor Module (Active Low) has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard comparator circuitry does the processing and the green indicator LED comes to life. The module features a 3 wire interface with Vcc, GND, and an OUTPUT pin on its tail. It works fine with 3.3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal).
