Measuring O2 Sensor Signals | Know Your Parts

Based on the oxygen sensor voltage, the controller will increase or decrease the pulse width of the injector, which in turn will change the oxygen sensor voltage for the next injector pulse. The oxygen sensor is also referred to as a lambda (l) 1 sensor. Lambda is the Greek letter equivalent to “L”. Lambda (l) 1 is the reference voltage of 450 mV. l 1 represents an air-fuel ratio of :1 ...

About TVOC and the Laser Egg+ Chemical

How the Laser Egg+ Chemical measures TVOC? A metal-oxide-semiconductor(MOS) sensor is used in the Laser Egg to measure TVOC concentration. To ensure measurements remain accurate throughout the sensor’s lifetime, the sensor is continually self-calibrating: the lowest reading is used as a baseline, and all given TVOC readings are relative to this baseline. For the first 5 minutes of powering ...

Understanding TVOC: What You Need To Know About Volatile ...

The heating of oil during cooking can make your TVOC readings skyrocket. With an air quality monitor, you can spot trends in your TVOC readings and even discover potential sources of VOCs. For example, TVOC readings often increase sharply during cooking; many cooking sprays and heated oils will produce VOCs. With an air quality monitor, you will know when it is best to vent out VOCs and which ...
