![]() ![]() ![]() Due to these serious limitations, I won't be able to use NDIR sensors. The NDIR sensors are costly, in the range of hundreds of euros / dollars for a single sensor, and would usually target a single gas only. Considering this is a battery powered application, and that we might need to be able to turn some of the sensors on and off depending on the measurements we are interested in, using semiconductor sensors might be challenging. The semiconductor sensors use a lot of power on the filament and have a long pre-heating time. Dust sensors are also quite big for the enclosure I am planning for these devices:įor gases, I have two options: affordable, low size semiconductor sensors or costly NDIR sensors. I have sorted out the radiation sensors and I'm happy with the alpha and beta radiation solutions, but I am still trying to find a reasonable way for detecting various gases. I was hoping to have better luck by now with the sensors. ![]()
