There's value in automation across different devices. Just a silly example: I've got a CO₂ monitor in my office. If the level goes above a certain threshold, it triggers a fan and changes the color of an LED light strip to alert me.
- smolder 6y agoAutomation is great. What's nice is the thing you described can also be implemented extremely cheaply without any fancy logic or network connectivity, and then it's just a Thing, not an IoT thing.
- monsieurbanana 6y ago... Are you really using iot for a co2 sensor of all things? It's one thing if your smart toaster fails to start when your car enters the garage, it's another when a device to save your life decides to do an npm update at the wrong time and you go to sleep. For good.
- Filligree 6y agoThis is probably to keep CO2 below 500/600 ppm, not a safety device.
- wl 6y agoSitting in an increasingly concentrated puddle of my own CO₂ when I close the door of my small home office is not a life safety issue. It just seems to affect my cognitive performance at some point. If there were CO₂ tanks or combustion in play, I'd be using a proper industrial CO₂ alarm.
- adrianN 6y agoCO2 is pretty safe because your body has a built in sensor.
- wbradmoore 6y agoare you thinking of CO?
- filleokus 6y agoSlightly OT: But what sensor are you using? I've been on the lookout for one for years but always decided they've been too expensive. But now working from home I think it's time to finally get one.
