Remember when a work meeting was just a group of people filling a poorly ventilated small room with their exhaled breath? Going back to the good old days, all you worry about is being lulled to sleep by endless slides and accumulation of carbon dioxide. now? Well, the stakes may be higher.
In either case, know the CO2 The level in the room may be a convenient data point, which is Portable CO2 Sensor like this May be useful.Or at least this [KaRMaN]SYPHCOM’s reason, “simple and powerful handheld carbon dioxide meter”. The internal structure of the sensor is almost what you expect-an Arduino Pro Micro, a SenseAir S8 CO2 The sensor board, as well as the necessary battery and charging circuit. But this build does break the pattern in several interesting places. One is the choice of display-the LED matrix display in the 1980s. HDSP2000 looks like a good desktop instrument, and it is very clear without a filter. It looks like it flickers a bit in the video below, but this is most likely just a camera artifact.
Another nice part of this version is the obvious care [KaRMaN] Make it as small as possible. The layout of the circuit boards and components is very clever, even without a shell, making it a sturdy, compact package. We have seen CO2 Sensors with more functions, but in order to quickly check air quality, SYPHCOM seems to be a good tool.
