Ask HN: What sensors do you have in your home?

I have none. I'd never put any in my home unless I had complete control over them. Same goes for digital assistants, no Google home or Amazon echo for me.

My home-made flatulometer is calibrated in sniffs per minute, but the family does not like the calibration experiments.

I hope you have smoke alarm at least.

Temperature and humidity. I'm looking into building a PM10 sensor.

I have a bunch of wireless temperature and humidity sensors in my apartment: http://blog.tafkas.net/2012/10/03/gathering-and-charting-tem...

None, I have my physiological senses and that is enough for me.

I don't want a sensor telling me one room is 1C colder than another room. Or controlling my light. Same goes for the Amazon Echo wiretapping for the CIA.
