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

Sensor module - Sampling the environment data, including laser PM2.5 sensor, Temperature/humidity sensor SHT30, CO2 sensor Senseair-S8, gravity sensor ADXL345. MCU controlling module is responsible for all Laser Egg+ CO2 Smart Air Quality Monitor controlling. MARVELL88MW302 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. Display module includes a LCD screen 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+ CO2 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. 2Sensor introduction:

Laser Egg+ CO2 Smart Air Quality Monitor uses a particle sensor based on laser scattering. 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. System operations:

Refer to the below chart for Laser Egg+ CO2 Smart Air Quality Monitor opertations 1. Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions. 2. Adapter shall be installed near the equipment and shall be easily accessible. 3.
