Ultra fast CO2 sensor

 GSS' SmartIR technology has enabled it to create a sensor that can take up to 20 readings per second, which is said to be a world record for NDIR CO2 detectors, and has a six times faster response rate than the current SprintIR.  

Ralph Weir, GSS' CEO, said: "We are the only company producing CO2 sensors using LEDs and photodiodes and, as we make the LEDs and photodiodes ourselves, we have been able to develop ultra-fast response times that no other NDIR sensor can match. Typical NDIR CO2 detectors take several seconds or even minutes to take a reading - because they use slow-reacting IR sources, which need time and energy to warm up, like MEMS hotplates, micro-bulbs or filament-based micro-lamp technologies. Our LEDs, by contrast, are Solid State emitters, and illuminate almost instantly."

Applications include factories where CO2 is used for modified atmospheres to delay packaged food from spoiling, as the sensors can provide ultra fast detection of rising CO2 levels.
