Modular Air Quality Detector

Abstract

The invention relates to a modularized air quality detection instrument. The modularized air quality detection instrument comprises interface mechanisms, a sensor module, a central processing module and an energy source module, wherein the interface mechanisms have mechanical, electrical and data connection functions, are respectively arranged in the middle of each module and are used for realizing rapid, firm and easily-detachable plugging of each module and simultaneously finishing the connection of power supplies and data of the modules; and grooves and protruded points which surround screw holes are respectively formed in the top and bottom surfaces of each module and are in positional correspondence with one another, and when the modules are overlapped, the protruded points are embedded into the grooves so as to fix the modules. According to the modularized air quality detection instrument, a plurality of modules can be selected to build a corresponding air detection system according to use requirements and environments.

Description

technical field [0001] The invention relates to a modular air quality detector, in particular to an interface mechanism with mechanical, electrical and data connection functions and a modular air quality detector including the interface mechanism. Background technique [0002] The society's increasing attention to air quality and the production of small sensors with measurement accuracy close to professional equipment have led to the emergence of air quality detectors for individual users. This type of air quality detector is characterized by low price, speed, and small size. Meet the needs of individual users to detect the air quality of their environment. The existing technical solutions have the following problems: 1. The air quality sensor has a service life problem. For example, the working life of the laser particle sensor is about three years. After the service life is exceeded, the entire air quality detector can only be scrapped. 2. The function is single. Most of ...

AI Technical Summary

Problems solved by technology

The existing technical solutions have the following problems: 1. The air quality sensor has a service life problem. For example, the working life of the laser particle sensor is about three years. After the service life is exceeded, the entire air quality detector can only be scrapped

2. The function is single. Most of the products only have the function of real-time display and cannot record the data within a certain period of time. A few products have the function of sending the detection data to the designated server in real time through the Internet. However, when the network is unstable or there is no Internet access condition Data logging is not possible in the case of

3. Poor continuous working ability in an environment without external power supply, unable to achieve uninterrupted monitoring for more than four hours
