5 HVAC sensors you need to know about - Primex HVAC Venting

Carbon dioxide sensors use either infrared light or a chemical process to measure levels of CO2. Sensors are also used to detect volatile organic compounds (VOCs). VOC sensors use a process called photoionization. Ionization is the changing of an atom’s charge. VOC sensors can ionize particles with ultraviolet light and measure electron levels. These measures allow them to detect toxic or ...

How to Reset the ECU After Changing an O2 Sensor | It ...

The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you've replaced your vehicle's O2 sensor, you'll need to reset the ECU so it can properly gather information from the new O2 sensor.

CO2 Gas Sensor Troubleshooting and FAQs - Technical ...

21/04/2014· Based on hands-on time with CCS811 CO2 sensors, I would recommend against them. They tend to drift high, sometimes way high, and then come back to their senses and provide reasonable readings when reset. I've tried two batches of CJMCU-811 sensors, purchased months apart (hoping to get a different manufacturing lot), and they were all rubbish.

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 …
