MQ2 Sensor (FC-22) Smoke/CO2/LPG - ArduinoForum.de

Input: mq_pin - analog channel Output: Rs of the sensor Remarks: This function use MQResistanceCalculation to caculate the sensor resistenc (Rs). The Rs changes as the sensor is in the different consentration of the target gas. The sample times and the time interval between samples could be configured by changing the definition of the macros.

LPG Gas Leakage Detector using Arduino Uno: Project with ...

23-06-2015 · We have used a LPG gas sensor module to detect LPG Gas. When LPG gas leakage occurs, it gives a HIGH pulse on its DO pin and arduino continuously reads its DO pin. When Arduino gets a HIGH pulse from LPG Gas module it shows “LPG Gas Leakage Alert” message on 16x2 LCD and activates buzzer which beeps again and again until the gas detector module doesn't sense the gas in environment.

Interfacing Gas Sensor (MQ2) With AVR - …

As MQ-2 sensor has heater inside, it is prefer to give power to the sensor from separate source. For stable operation sensor requires around 24 hour preheating. We can use Ultra AVR Developement Board,Starter AVR or Atmega32 Breakout. Code. Resistance value of MQ-2 is difference to various kinds and various concentration gases.
