Sonoff PM25

How clean is the air in your home really? Most of the time we assume everything is fine — but tiny particles like PM2.5 pollution are invisible and can seriously affect your health. In this video I test the Sonoff AirGuard, an affordable air quality monitor that measures PM2.5, PM10, temperature and humidity, and supports Matter smart-home integration. After two months of real-world testing, I’ll show you exactly how it performs — including some unusual stress tests with incense smoke, dust, vacuuming, and everyday indoor pollution. We’ll also talk about the Plantower laser particulate sensor inside, the software experience with eWelink and Home Assistant, and whether this device is actually accurate — or if there are better alternatives like the IKEA VINDSTYRKA. If you care about clean air at home, smart-home sensors, or improving indoor air quality — this video will help you decide whether the Sonoff AirGuard is the right choice. 📸 Chapters: 00:00 – Intro 00:40 – What does the AirGuard measure? 01:05 – Design & build quality 02:30 – Tech specs & sensor inside 03:42 – Smoke & dust stress tests 05:17 – Software: eWeLink 05:45 – Home Assistant setup 06:40 – Downsides 06:20 – Final verdict (Sonoff vs IKEA) 🎥 Subscribe for more honest tech reviews! 🔔 Turn on notifications so you don’t miss my next smart-home or gadget inspection. 🏠 More smart-home tech: https://www.youtube.com/watch?v=HcKvg0GebL0&list=PLczsTBo27jX69EOTcResYoBsUhKFcQ7DP 📦 SONOFF AirGuard Air Quality Monitor: https://geni.us/Sonoff-PM25 🛠️ Recommended gear: 📸 Great CAMERA for YouTube: https://geni.us/mycAm 📸 A bigger CAMERA: https://geni.us/nHrgUik 📱 My favorite SMARTPHONE: https://geni.us/8zgx 🚁 DJI’s awesome DRONE: https://geni.us/44pgOd ⌚ My favorite SMARTWATCH: https://geni.us/5l7I 📷 A cool ACTION CAMERA: https://geni.us/EAjPFi 📷 The best 360° CAMERA: https://geni.us/One-X2 🚴 My SCOOTER: https://geni.us/5AC67Y 🎥 The GIMBAL: https://geni.us/DRjj 🎵 Music used in this video: https://geni.us/Epidemic_Sound ٩(-̮̮̃•̃)۶ 💬 Enjoyed the video?
