2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4. Essential features FLAME click 2 3 Flame click can operate in two ways. It can output a continuous analog signal from the phototransistor, or send an interrupt to the target board MCU. The onboard potentiometer allows you to set the exact threshold that will trigger the interrupt. This will require some fine tuning as the phototransistor will be sensitive to the surrounding thermal radiation. Properly Turn the board upside down so that Turn the board upward again. Make sure calibrated, flame click can be used in a variety the bottom side is facing you upwards. to align the headers so that they are of safety applications. Fire sensors based on Place shorter pins of the header into the perpendicular to the board, then solder the phototransistors have a faster reaction time appropriate soldering pads. pins carefully. compared to smoke or heat detectors. 1. Introduction 3. Plugging the board in click Flame click is a fire detection solution. It carries Once you have soldered the headers your a PT334-6B NPN silicon phototransistor thats board is ready to be placed into the desired BOARD covered in black epoxy and therefore sensitive mikroBUS socket. Make sure to align the cut www.mikroe.com only to infrared light. A potentiometer lets in the lower-right part of the board with the you calibrate the sensor for its specific markings on the silkscreen at the mikroBUS FLAME click manual environment. The board communicates with socket. If all the pins are aligned ver 1.01 the target board microcontroller through the correctly, push the board mikroBUS AN and INT pins. It can use both a all the way into the socket. 0100000073636 3.3V or a 5V power supply.VCC 5. Schematic VCC VCC 7.
