The new sensor comes with response rates that had never been reached before by any other NDIR CO2 sensors. It can take up to 20 readings per second, and has a six-times faster response rate than the current SprintIR.
According to Ralph Weir, GSS’ CEO, the sensor uses LEDs and photodiodes to measure differential light absorption between light at 4.2 and 4.4 μm. So, they succeeded to develop ultra-speed sensor, while other detectors take several seconds or even minutes to take a reading.
The SprintIR6S is less than a cubic inch in dimension with 23.8mm in diameter and 24mm tall. It operates at a range between 3.25V and 5.5V and consumes only 35mW. SprintIR6S is also available in measurements ranges from 0% to 100%.
