Jól kalibrálható érzékenység.
Alkalmas robotok tűz és irányának detektálásra, hobby tűzjelzésre, stb.
Példa alkalmazás:
Egy hagyományos öngyújtó lángját 1m-ről is érzékeli zárt térben, viszont 50cm felett ilyen kis lángnál már holt terek lehetnek a szenzorok között, így az iránya nem biztos, ennek megfelelően érdemes kalibrálni. Nagy érzékenységnél a kültéri napfény infra sávja már zavarhatja, ezért vagy sötétben, vagy napfénynél kis érzékenységgel célszerű használni.
DESCRIPTION
Use this module to detect a flame in large range (>120 degree). Perfect if you want your robot to detect if there is any fire around. It detects fire with the 5 flame sensors which are arranged in 120 degree detection range, with each sensor providing a 30 degree detection range. This module outputs an analogue signal, which can provide a very precise reading on each sensor, and also a digital signal which is very easy to use, you can adjust the digital output sensitivity by the on-board potentiometer. The 5 LED indicators are helpful in debugging and testing.
Specification
Voltage:3.3V - 9V
Analogue & Digital outputs
On-board potentiometer and indicators
Detecting range: >120 degree
Working Principle:
This product is capable of detecting short-wave near-infrared (SW-NIR) waves with a range of 700-1100 nm from the flame and outputting them via electrical signals (voltage signals).
Features:
1.Using a five-way flame sensor design, the detection range is wide (the detection range of a common single flame sensor is about 30°, and the range is gradually reduced as the distance increases, the detection range of this product is greater than 120°)
2.Can output digital signals (high and low level), easy to use
3. can output analog signal (voltage signal), can measure signals more accurately, suitable for high precision occasions
4. Five-way output all have status indicators, which makes great convenience in debugging or in actual operation.
5. Digital output detection distance is adjustable, analog output sensitivity is adjustable, design is more flexible
6. Adopts 1% resistor design (the flame sensor on the market is designed with 5% resistor), the signal output is more accurate, suitable for occasions requiring high precision measurement.
7. Onboard 3 M3 mounting holes for easy installation
8.3.3V-9V power supply, compatible with most single-chip systems
9. SMD devices are all fully automatic welded by SMT process, and the quality of military products is trustworthy.
10. Applications: All occasions required for flame detection.
11. Use Cases: Fire extinguishing robot/Flame alarm
