MQ7 Carbon Monoxide Gas Sensor HobbyTronics

The MQ7 Carbon Monoxide Gas Sensor detects the concentration of Carbon Monoxide gas in the air and ouputs its reading as an analog voltage. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Connections. Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B ...


How to Use the MQ7 Carbon Monoxide Sensor ...

Introduction to MQ7 Carbon Monoxide Sensor. According to its datasheet, the MQ7 carbon monoxide sensor detects 20 to 2000 ppm of CO in air. Here is its sensitivity characteristic curve: This is a graph of Rs/R0 vs. gas concentration in ppm. Rs is the resistance of the sensor in target gas while R0 is the resistance in clean air. We will use this graph later when we create our code. For this ...

Sensor Alarm w/ Threshold Control Seven Segment Display

NOTE: This project shows a MQ7 CO gas detector in use because this is the only working gas detector that I have. The MQ7 sensor requires an alternating and 5v, which needs to be achieved via pulse width modulation (PWM). That feature is not present in this project, and I intend to substitute a methane sensor (MQ4) for the MQ7 when it arrives from China. FAQ; About; Contact; seawarrior ...

Grove Gas Sensor(MQ2) Seeed Wiki

The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.
