- crazygringo 3y agoUsually yes. PM2.5 sensors are usually the common denominator across all consumer air sensors.
- lathiat 3y agoMost of the $60 ones aren’t really measuring CO2. The usual giveaway is if the sensor also measures VOC or TVOC most are estimating the CO2 based on that. Which has only a vague correlation sometimes and not remotely close to useful. You need a device that specifically quotes having an “NDIR” sensor and most are $100+
- Mutlut 3y agoThe one i mentioned btw. only hsa that NDIR sensor and is at 60 bucks: "Hochwertiger NDIR Dual Beam Sensor" <> "high quality NDIR Dual beam sensor" And it doesn't meassure anything else. So a good point that its not the same thing and if you want both, you probably need to spend 100+
