The indoor air quality sensor can measure indoor PM2.5, formaldehyde, temperature and humidity and other parameters, with accurate measurement, temperature compensation, automatic alarm and other functions.
(1)Fast detection of formaldehyde / PM2.5 / carbon dioxide, large screen high-definition display, focus on air quality detection；
(2)Imported detection module, using imported temperature and humidity detection module, PM2.5 using laser detection principle, accurate measurement；
(3)Anti interference technology, using high-precision anti-interference intelligent chip, factory calibrated by thermostat, monitoring accuracy, small error；
(4)Double alarm function, when the data is lower or higher than the set value, the corresponding data font will turn red, and the built-in buzzer alarm will give an alarm;
(5)2.8 inch TFT color screen large screen, display read intuitive, at a glance, real-time display of air quality, built-in high-precision clock module;
(6)1500mah large capacity lithium battery, long life, long time standby, portable measurement, easy to use;
(7)USB power supply mode, can detect while charging, 24-hour uninterrupted work, can also be fully charged, reuse.
Indoor air quality sensor is widely used in new car / new house / old people's room / mother and baby room / children's room / school / office building, hotel and other environmental testing places.
