Carbon Monoxide: What You do if Your Detector Goes Off

· (Most CO deaths occur during sleep.) A reliable detector monitors tiny fluctuations over a certain stretch of time and shrieks only when the cumulative amount of CO exceeds safe levels. When your detector goes off, it will sound like intermittent beeps. It will keep going off until the CO levels drop, or you push the mute button.

Typically, NDIR CO2 sensors use the strong absorption of CO2 around m, a wavelength range where no other common molecules absorb, thereby avoiding cross-sensitivity issues. Due to these advantages, 83% of the European advanced CO2 sensor market uses NDIR sensors [4]. However, NDIR sensors tend to be bulky as a long (typically several cm) interaction length is required to …

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. Step 1. Open the fuse ...
