2 1. General safety overview 1.1 Precautions for installation and transportation Identification Description Remarks ELECTRIC SHOCK RISK The chassis shell should be grounded at installation. Installation is strictly prohibited when it is powered on, otherwise short circuit may occur. Do not operate when it is power on and ensure safe grounding. ATTENTION The equipment should be installed in a clean place which is free of corrosion or violent vibration to reduce equipment contamination, corrosion, and violent vibration. The equipment should be properly installed to make sure that it can support the weight of the host, and should be in strict accordance with the installation instructions. Make sure the installation is reliable and secure. Avoid violent collision and vibration at handling. It should be handled with care to prevent against damage to the parts. It can only be handled after the chassis door is closed to avoid personnel injury. The chassis cover is prone to squeezing other items or human body. Avoid foreign matters falling into the equipment during the installation process since they may cause short circuit in the chassis or malfunction.

Waterproof Parts can only be replaced by conforming or specified ones, otherwise it will cause failure or malfunction. Choose conforming parts. The scrapped parts should be handled with according to relevant regulations. Environment protection should be taken into consideration while handling with the scrapped parts. Please maintain and calibrate the instrument regularly. INFO If you failed to fix the problem by following the instructions of the Manual, please contact the seller or our technical staff. Unauthorized disassembly may cause an accident or permanent damage to the product. 2. Product overview The micro environment quality monitoring station can be used for measuring the concentration of PM2.5 and PM10 particles, as well as pollutant gas such as SO2, NO2, O3, CO and TVOC under outdoor atmospheric environment. It can monitor environmental parameters, including temperature, humidity, air pressure, etc. Relying on the ARM CortexM3 processor, Internet of things, sensor technology and GPRS wireless communication technology, the instrument can collect the mass concentration of the particles in the air in real time, and transmit the data to the cloud server through GPRS wireless transmission.

6 4.3 PID principle TVOC gas detection is based on PID photoion principle. The PID sensor consists of main parts such as ultraviolet light source and ion chamber. The positive and negative electrodes are allocated in the ion chamber to form an electric field. The organic volatile molecules are excited by high-energy ultraviolet light source to generate negative electrons and positive ions. These ionized particles form current between the electrodes. The current signal will be output through detector amplification and processing. And finally, ppm level of concentration can be detected.
