Functions of the wireless Air Quality sensor
This Air Quality sensor is a precision instrument that displays Air Quality Index (which help to understand what local air
quality means to health, and the table below shows the detailed information), color indicator, health level and comfortable
face icon. And the device transmits the data continuously to the receiving unit to bring you the latest information. This
product adopts wireless 433 MHz technology, which can transmit data at the maximum distance of 30 meters (100 feet) in
an open area.
