Usage: These types of sensors are used for short range fire detection and can be used to monitor projects or as a safety precaution to cut devices off / on.Range:I have found this unit is mostly accurate up to about 3 feet.How it works:The flame sensor is very sensitive to IR wavelength at 760 nm 1100 nm light.Analog output (A0): Real-time output voltage signal on the thermal resistance.Digital output (D0): When the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer.Pins:VCC. Positive voltage input: 5v for analog 3.3v for Digital.A0. Analog outputD0.
Build fire alarm or fire detector using Flame sensor and Arduino board, the sensor basically detects IR (Infra Red) light wavelength between 760 nm – 1100 nm (nano meter) that is emitted from fire flame.
Digital outputGND. GroundDimensions:1.18 in x 0.59 in x 0.20 in (3.0 cm x 1.5 cm x 0.5 cm)Weight:0.28 oz (8 g). The following code maps and reads the analog values given by the flame sensor (0-1024). The stock flame sensor will have the following reaction with this code:. If holding a flame within 1.5 feet in front of the sensor; 'case 0' will be activated and '. Close Fire.
' will be sent to the serial monitor. If holding a flame between 1.5 feet and 3 feet in front of the sensor; 'case 1' will be activated and '.Distant Fire.
' will be sent to the serial monitor. If no flame is detected in front of the sensor; 'case 2' will be activated and ' No Fire ' will be sent to the serial monitor. To view the output, point a serial monitor such as Putty at your Arduino. This code is constantly updating in order to provide a real time feedback of the flame sensor.Code:. Attached due to formatting.Attachments. Hi Reichenstein7,I building an outdoor project using this type of sensor on a propane burner. Looks like this sensor is very sensitive to daylight which impairs its ability to distinguish between daylight with and without a flame in front of it.
Any ideas for a flame sensor which would not be daylight impaired? I thought about using a thermocouple, but a LPG propane burner flame is around 3500 deg F and most thermocouples won't be able to deal.
I thought about maybe a laser type sensor, but not sure what happens to a laser when it's pointed through a 'blue' (400-500 nm) flame, vs not. Or are there other flame sensors that would be better suited to detect a flame in daylight?Any advice you have would be much appreciated.
FromThe FL3101H is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet (UV) spectral range for optimized speed of response. Configurations with dual Modbus and HART are. Device Classification: Sensor. Field of View (Vertical/Horizontal): 120° Max. Conical (FL3100H); 140° Max.
Conical (FL3101H). Max Response Time: 1.00 to 3.00.
Sensor Technology: UV Detector Only. FromSierra Monitor ’s 3600-M flame detector monitors hydrocarbon and hydrogen flames at long distances with the highest immunity to false alarms. The 3600-M uses infrared (IR) technology, a reliable design that provides early warning of flaming fires and immunity to false alarms from IR sources. Device Classification: Sensor. Max Detector Range (Sensitivity): 33 to 215. Max Response Time: 5.00. Field of View (Vertical/Horizontal): Gasoline: 67° Horizontal, 70° Vertical; Hydrogen: 80° Horizontal, 80° Vertical.
