Hardware introduction The system structure of Laser Egg+ CO2 Smart Air Quality Monitor is shown in below diagram. The air quality monitor consists of:

Emas) 0t mnae J meare o io Lithhn ty rems masir soee us @ Sensor module — Sampling the environment data, including laser PM2. 5 sensor, Temperature/bumidity sensor SHT3O, CO2 sensor Senseair—§8. gravity sensor ADXL34S5. @ MCU controlling module — is responsible for all Laser Egg+ C0O2 Smart Air Quality Monitor controlling. MARVELLSSMW302 processor is used as the MCU. It is used for data format parsing, PM2.5 concentration calibration, adjusting the working mode of the Laser Egg+ CO2 Smart Air Quality Monitor based on the signals from the gravity sensor, and to switch the displays in the system according to the manual intervention via the buttons C) Display module — includes a LCD sereen and the UI buttons. The screen can display the PM2. 5 values in three modes, and also the battery state including charging and discharging @ Communication module — Wi—Fi module. It is used for the remote communication of Laser Egg+ C02 Smart Air Quality Monitor. It can upload the data acquired by the multiple air sensors, and also receive the commands sent by the user via app on smart phones (:) Power module — including the lithium battery system, charge/discharge management chip. It is used for the power supply of the whole system 2 . Sensor introduction: Laser Egg+ CO2 Smart Air Quality Monitor uses a particle sensor based on laser seattering The sensor contains a laser generator and a photoelectric receiver It can convert laser scattering caused by the particles to electrical signals, which are calculated into particle counting and concentration with algorithms

Laser based particle sensor is considered to be more accurate among all scattering particle sensors. CO2 sensor is based on non—dispersive infrared monitoring technology. The S8 sensor by Senseair is considered to be a high—end sensor. 3.
