Ceiling fanatics appear to be an oft-misunderstood or lost sight of family equipment. As such, they appear to have neglected numerous the IoT wave. Certain, you’ll be able to get sensible controllers for them to plug into your house automation machine of selection, however those most commonly depend on temperature sensors, easy timers, or voice instructions. There’s much more to a ceiling fan than keeping up a at ease temperature, as [EJ] demonstrates with this smarter ceiling fan construct.
A large a part of the activity of a ceiling fan is to reinforce air circulate, which is able to assist a room from feeling “stuffy”. This sense is normally brought about through extra CO2 because of breathing in a space the place the air isn’t shifting sufficient to exhaust this fuel. Now not simplest does [EJ]’s controller employ a temperature track for controlling the fan routinely, however there could also be a CO2 sensor built-in to reinforce this side of air high quality when wanted.
All of the construct is in line with a Raspberry Pi 0, and not anything had to be modified in regards to the ceiling fan itself for this added capability as it already incorporated a radio-based far flung keep watch over. With some tracking of the alerts produced through the far flung, the Raspberry Pi used to be programmed to imitate those instructions when the encompassing sensors captured a situation the place [EJ] would need the fan on. There’s additionally a handbook keep watch over button as smartly, so the fan keep watch over isn’t fully within the palms of the pc.
For slightly extra detailed details about this construct, there’s a separate venture web page which main points numerous the details about the RF waveform taking pictures and sport. And, if you wish to take your fan to the following degree, check out this one that makes a speciality of development a smartphone app to keep watch over the fan as an alternative.
