Air quality detection device based on narrow-band internet of things

Abstract

The invention relates to an air quality detection device based on the narrow-band Internet of Things. The detection device comprises an MCU, an NB-IoT module, a GPS module, an air quality sensor module, an SD card, a touch screen, a power supply and a server. The MCU is used for processing control signals sent to each module and carrying out data exchange processing; the air quality sensor moduleis used for collecting PM2.5, formaldehyde, TVOC, CO2 and temperature and humidity data in the environment and sending the data to the MCU; the GPS module is used for sending latitude and height datato the MCU; the NB-IoT module is used for uploading the air quality data and the positioning information sent by the MCU to the server; and the power supply is used for providing power for the whole device; the SD card is used for storing various data and parameters; and the touch screen is used for being driven by the MCU and displaying an interactive interface. Compared with the prior art, the air quality detection device has the advantages of being easy to deploy, short in debugging time, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of air quality detection, in particular to an air quality detection device based on narrowband internet of things. Background technique [0002] Air detection in a broad sense refers to the detection of air components. Air detection in a narrow sense mainly focuses on indoor air detection from the perspective of application. It refers to indoor decoration materials, furniture, etc. containing harmful substances to the human body, which are released into the home and office environment to cause decoration pollution, to detect air quality. [0003] At present, in order to monitor data such as PM2.5, formaldehyde, TVOC, CO2, temperature and humidity in the air within a fixed period of time, large monitoring boxes are often used, and complicated lines need to be laid and long-term system debugging is required when erecting and deploying. It is impossible to quickly establish a monitoring network in a certain a...

[0003] At present, in order to monitor data such as PM2.5, formaldehyde, TVOC, CO2, temperature and humidity in the air within a fixed period of time, large monitoring boxes are often used, and complicated lines need to be laid and long-term system debugging is required when erecting and deploying. It is impossible to quickly establish a monitoring network in a certain area to monitor air quality immediately

The home air quality monitor can only be used indoors and cannot be deployed outdoors
