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 ...

Measure CO2 & TVOC using CCS811 Gas Sensor & Arduino

2021-02-08· In this tutorial, we will interface CO2 & TVOC Gas Sensor CCS811 with Arduino & measure CO2 & TVOC in the air. The CCS811 Air Quality Breakout Board is a digital gas sensor capable of sensing a wide range of Total Volatile Organic Compounds (TVOC) & equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels. We can thus use this sensor to identify the air quality whether …
