2016-01-11· Since the oxygen sensor output helps control engine timing, combustion intervals, and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle and other engine-related issues. When to replace the sensor. If your vehicle was manufactured within the past 15 years, the oxygen sensor should be replaced every 60,000 to 90,000 miles. This ...
The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means it's a lot bigger and more expensive, but it is the real thing ...

Small NDIR CO2 sensor breakthrough. An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor …
If you notice any of the following signs, you may have a bad O2 sensor or one that is about to go bad: An illuminated check-engine light; A rough engine idle; A misfiring engine; Worsening fuel economy; Failed emissions inspection; Even if your car’s engine is not exhibiting any of the above oxygen sensor symptoms, it may still be time to replace your existing ones. In simple terms, O2 ...
The NDIR sensor used in the proposed system is a Alphasense sensor is composed of an IR lamp, two thermopile channels, and a thermistor which is used for temperature calibration. To save power and to avoid overheating the device the lamp source is modulated typically with a 50% duty cycle with a frequency of 1 to 3Hz. The Detector (Active) and Reference channel output are connected ...

Abstract: In this paper, we propose a novel, miniaturized non-dispersive infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor has a simple structure, consisting of a hollow metallic cylindrical cavity along with access waveguides. A detailed analysis of the proposed sensor is presented. Simulation with 3D ray tracing shows that an integrating cylinder with 4 mm diameter gives ...

Although it looks like a retro Nokia, this air quality tester really comes in handy for measuring CO2 levels, temperature, and humidity. The NDIR sensor claims to provide very accurate readings, so that the device is also compatible with reading the environmental conditions in an office, as well as a lab.
In our industry, many of us use the term "NDIR CO2 sensor", without thinking about what it stands for, or how NDIR sensors actually work. NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure CO2. An infrared (IR) lamp directs waves of light through a tube filled with air toward an IR light detector, which measures the amount of IR light ...
