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 module. The highly reflective coating ensured that the CO2 …
Smart sensor suitable for wireless applications. The GasSense NDIR gas sensor, with integrated transmitter, is an innovative measurement module for the detection of CO2, CO, N2O, CH4 or related hydrocarbons. The sensor can be easily integrated as an OEM component into controls, measurement systems and monitoring instruments.
· comparing NDIR sensors with two commonly applied methods, a Photo-Acoustic Spectroscope (PAS) Gas Monitor and an Open-Path laser (OP-laser). First, calibrations for the NDIR sensors were obtained in the laboratory. Then, the NDIR sensors were placed in a dairy cow barn for comparison with the PAS and OP-laser methods. The main conclusions were: (a) in order to represent the overall barn CO2 ...
You want an NDIR CO2 sensor such as an SCD30 or a T6713 and not an electrochemical sensor. Electrochemical sensors respond to CO2 and other VOC gases and give you an "eCO2" reading, and you can never be really sure if it measured CO2 or something …

NDIR gas sensors utilize the absorption of infrared light by gas molecules. Many gases have absorption spectra in the infrared region (Fig. 1) and can therefore be measured by optical sensors. Figure 2 shows the schematic set-up of an NDIR gas sensor. A light source emits infrared light which passes through a gas chamber. In the gas chamber the ...
This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent performance to a conventional dual-channel CO2 sensor…

(NDIR) Spectroscopy with lead selenide (PbSe) photodetectors . May 26, 2020 – Ludwigshafen, Germany – In today’s world, carbon dioxide (CO. 2) concentration measurement has become important, if not vital, in a wide range of applications. These include capnography for medical diagnosis, environmental (indoor/outdoor) pollution monitoring, heating, ventilation and air conditioning (HVAC)as ...
Visit us on this year's Sensor+Test fair, which will take place online this year. From 4th to 6th May, you can easily get in contact with one of our technical experts and ask anything about thermopile sensors, infrared arrays and thermopile modules as well as pyroelectric and vacuum sensors.
· Hello everyone. I'm working on a project that has to have a co2 sensor detect average amounts of atmospheric co2. It uses many other sensors, including gas sensors, and I have not had any real problems connecting any of them until I got to the MG811. I have been troubleshooting this for days now, the main problem resulting from lack of documentation and detailed guides.

· Also consider that's this is not a CO2 sensor, and for that reason using the datasheet values without any NDIR sensor corralation could bring to inconsistend data. Said that, It could be interesting to log that data and correlate it if you are planning to use this sensor for outdoor use, or when ambient temperature is less than 10 degrees.
· If a bad oxygen sensor disrupts the air to fuel ratio mixture, or too much fuel is injected into the engine, your vehicle's gas mileage will be reduced. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust. If yourself filling up your gas tank more often, keep a record of how many gallons you fill up with and how often. If ...

The Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity. It can be used in a variety of biology experiments. It connects via Bluetooth® wireless technology or via USB to your device.
· CO2 sensors should use Non-dispersive infra red (NDIR) principles, the VOC based values are estimates based on the VOC level, and commercial modules are more than good enough to measure residential variances. That means the MH-Z19B is using the correct technique. I quite like the results coming from it, as long as you disable the autocalibration.

An oxygen sensor does not have to fail completely to give you problems. On the contrary, even a failing O2 sensor (sometimes called a “lazy” O2 sensor) may cause your car to have a few issues. If you notice any of the following signs, you may have a bad O2 sensor or one that is about to go bad…
