    Flame Sensor Infrared Receiver

    0 out of 5

    The flame sensor infrared receiver module can detect a flame or light source of wavelength from 760nm to 1100nm. It is particularly useful in fire alarms. The sensitivity of the sensor can be adjusted using the potentiometer provided. The output is given in digital format. The circuit uses a LM393 comparator.

    Flammable Gas and Smoke Sensor

    0 out of 5

    MQ2 is a low cost semiconductor sensor which can detect smoke and flammable gases at concentrations from 300 to 10,000 ppm. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of combustible gases increases. This sensor has high sensitivity to Hydrogen, Propane, LPG, Methane and other combustible steams. This can be used to detect gas leakage in industries and houses. MQ2 gas sensor can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc using an Analog to Digital Converter (ADC).

    Smoke and Flammable Gas Sensor

    0 out of 5

    This sensor module is made using MQ2 Smoke and Flammable Gas Sensor, which uses Tin oxide (SnO2) as the sensor element. Tin oxide has a lower conductivity in clean air. When it comes in contact with flammable gases like LPG, hydrogen, butane, propane, alcohol, smoke and other combustible gases its conductivity increases. This module uses a simple circuit to measure changes in conductivity and output the same. It has dual signal output ie. analogue output and TTL level output. The module also provides a potentiometer to adjust the sensitivity of the sensor.
