How Does a TVOC Sensor Actually Work? - Kaiterra

What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact ...

Engine Coolant Temperature Sensor (ECT)

The normal value of the ECT sensor voltage is 2V at cold engine and at warm engine. A defect sensor can indicate a voltage of at cold engine and at warm engine, thus causing difficulties of starting a cold engine and a presence of rich fuel mixture when the engine is warm. This will not generate any fault codes (if the onboard controller is not programmed to detect voltage ...

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 ...

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 ...
