Flame Click Board
IC/module: PT334-6B silicon phototransistor
The PT334-6B NPN-polarity silicon phototransistor is covered in a dome-shaped black epoxy 5mm lens, which makes it highly sensitive to infrared light. This phototransistor has Maximum Emitter Collector Voltage: 5V; Maximum Collector Current: 20mA; Peak Wavelength 940 nm.
Fast Reaction Time
Being a phototransistor-based flame detector, Flame click is supposed to have a fast response time as compared to smoke or heat sensors in certain conditions (though a narrower sensing angle and shorter range). Due to this, it is seen as a better choice for monitoring spots prone to catch fire, like electric fuse boxes or motor boxes.
Requires Proper CalibrationFlame click boasts of high photo sensitivity but the user needs to properly calibrate the sensor to prevent it from reacting to the surrounding thermal radiation. For this, the user can use the onboard potentiometer that helps to set the exact threshold and trigger the interrupt for the target board microcontroller. After proper calibration, it can be used in a variety of security applications.
