PNI HS291 – Wi-Fi air quality and CO2 monitor
Code: PNI-HS291Product detailed description
PNI SafeHouse HS291 is a compact sensor that in real time monitors CO2 level, temperature and humidity and gives you an up-to-date overview of the air quality in your home or office. It is suitable wherever you want to keep a healthy environment under control and thanks to its functional design it fits into any space.
Accurate measurement and Tuya Smart app
CO2 concentration is measured by a highly accurate NDIR (non-dispersive infrared) sensor in the range of 400 to 5000 ppm with an accuracy of ±100 ppm or 10 %. The device connects via Wi-Fi (2.4 GHz) and is controlled by the free Tuya Smart app, which provides access to all functions. A backup Li-Ion battery of 1000 mAh ensures operation for up to 6 hours during a power outage.
Alarms and display
If safety thresholds are exceeded, an acoustic and visual alarm will immediately alert you, so you can act in time, for example to ventilate. The clear display shows time, temperature, humidity and CO2 level. According to the manufacturer, a concentration below 2000 ppm is considered good and above 2000 ppm as increased, which is also the alarm level.
