Flame click™ is a fire detection solution. It carries a PT334-6B silicon phototransistor that’s covered in black epoxy and therefore sensitive only to infrared light. To use it as a fire alarm, set up the exact detection threshold through the onboard potentiometer (once reached, the click will send an interrupt to the target board MCU through the mikroBUS™ INT pin). Othewise the sensor can also output a continuous analog signal through the mikroBUS™ AN pin. Flame click™ can use both a 3.3V or a 5V power supply.
