Led infrared sensor.
Detector of the source of fire or flame, can detect a flame or wavelength 760 nm-1100 nm
Particularly sensitive to the flame spectrum.
This optical flame sensor is a device that detects the existence of combustion by the light emitted by it.
Infrared LED Flame Sensor 5mm features:
- Range of light, Distance of 80 cm.
- Angle detection of about 60 degrees,
- This light can be detected by an optical sensor,
- Can be captured by digital inputs and analog inputs of Arduino.

- The PCF8574P is an 8-bit remote I / O expander for the I2C bus with 16-pin DIP packet interrupt. - Provides general-purpose remote I / O expansion via a two-wire, two-way I2C bus (Serial Clock (SCL), Serial Data (SDA)).
- Devices consist of eight quasi-directional ports , 100KHz I2C bus interface, three hardware address inputs and interrupt output operating between 2.5V and 6V.
- Quasi-bidirectional port can be independently assigned as one input to monitor interrupt status or keyboards or as an output to activate indicating devices like LEDs. - System Master can read from the input port or write to the output port through a single register.

It allows to save the record of any data.
It has a real time clock RTC, with battery included, so you can keep the date and time over the years and an SD notes reader, which accepts the format FAT16 and FAT32 to record your data. Logging Recorder Data Logger Module Shield UNO Mega SD Card features:
- Arduino data logging shield
- Data recording module to the FAT16 / FAT32 SD card
- Real time with RTC battery.
- SD card interface compatible with the FAT16 / FAT32 format
- Transmitter circuit level 3.3V.
- Compatible with Arduino UNO, Leonardo, ADK / Mega R3 or higher
