Digital IR Sensor Array 10RC |

Digital IR Sensor Array 10RC. If your Arduino Uno (that has only 6 ADC pins) is restricting you from buying a better 8 or 10 IR based analog line detection sensor, this product is for you. It’s similar to the polulu QTR8RC sensor, but contains more IR sensors. It has 1cm spacing between IR sensors and got a total of 10 sensors.


Gas sensor system for fire detection | Jordi Fonollosa

Nov 14, 2021· Nowadays, standalone CO sensors, smoke detectors, or a combination of these, are standard components for fire alarm systems. We explored the benefits of using gas sensor arrays for fire alarm systems. While gas sensor arrays are a valuable alternative for early fire detection, in practice, they have certain drawbacks—they can show low immunity to nuisances,…
