$230... the sensor monitors:
- particulate matter (PM2.5)
- CO2 concentration
- volatile organic compounds (TVOC)
- nitrogen oxides (NOX)
- temperature
- humidity.
vs IKEA sensor (VINDSTYRKA for $60).
- particles (PM2.5)
- temperature
- relative humidity
- total Volatile Organic Compounds (tVOC)
Fine enough product I suppose... but not sure that those 2 other sensors would ever be worth $170 more for me, especially since I have a CO2 monitor on one of my fire alarms on each floor... and those alarms have a z-wave relay on them. Especially since it's wifi and I prefer zwave/zigbee to keep the wifi less cluttered. The real site (https://www.airgradient.com/indoor/) mentions pm1 and pm10 but only in like one place and doesn't go into detail on that sensor in use or anything like that. So not sure about that. 2A power adapter requirement (non-included) seems excessive as well... They do claim that they will never lock in, that nice. They support their own software though... so there's always that risk I suppose of any ol' firmware update locking it down, though the certification hopefully proves that this won't happen. I bet it's more accurate than the VINDSTYRKA, but I'm not sure how much accuracy people actually need vs just monitoring the trend and triggering on spikes.
I'm more interested in finding an outdoor unit since air quality isn't often part of any weather station setup. This company has outdoor units, but they're all cellular and way expensive. Anyone know of a good outdoor unit?
