How To Make a Carbon Monoxide Detector With an MQ7 Sensor

The MQ7 CO detector is an analog component therefore, it’s connected to the Arduino ADC pin. The values read by the Arduino will be in the range between 0-1023. In order to translate the ADC values to PWM values (required by the LED) – 0-255, we use the map() function, which is then stored in mq7Val variable. Using this variable, we can determine which color we want to control on the LED ...

CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

29/03/2014· This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable voltage regulator to drive this.

Gas Sensor MQ-7 | SUNROBOTICS

Principle: MQ7 Carbon monoxide sensor can detect CO gas and export both digital (0/1) and analog signals to Arduino. The TTL pin will export low voltage when CO GAS is detected. The analog pin will export voltage that is correlated to CO Gas density. Schematic: Vcc to Arduino 5V pin . GND to Arduino GND pin . Output to Arduino Digital D8 pin . Output to Arduino Analog A0 pin. Procedure: Step 1 ...
