Problems solved by technology
However, the sensor it uses is also a low-precision infrared dust sensor
The solution of using the mobile phone audio interface to supply power and transmit data cannot drive a high-power high-precision laser particle concentration sensor (the power supply capacity of the mobile phone audio interface is generally only tens of mW)
In short, the current smart phone peripherals for air particle detection still need to be improved in terms of accuracy and other aspects

The invention discloses an air particulate matter external detection device and system. The device comprises a shell, and a detection module is arranged in the shell so as to detect the concentrationof micro laser particles in a current environment; a communication module is arranged in the shell and is connected with the detection module so as to send the concentration of the micro laser particles of the current environment to a mobile terminal. The device can be used for measuring the concentrations of particulate matter with different particle sizes at the same time and is small in size, low in weight, low in cost and high in safety, the size and the cost are reduced, display is attractive, detection is accurate, and the device is simple and easy to obtain.
Description
technical field [0001] The invention relates to the cross technical fields of information technology and environmental protection, in particular to a peripheral detection device and system for air particulate matter. Background technique [0002] At present, under the background of frequent smog and haze weather, people are very concerned about the air quality around them for health reasons, and hope to know the concentration level of air particles in their environment at any time, so as to take targeted measures for personal protection. [0003] In the field of air particle detection sensors, the related technologies of micro-laser particle concentration sensors are relatively mature and are gradually replacing low-precision infrared dust sensors. [0004] In terms of portable air particle detection equipment, the most common design currently on the market generally uses a laser particle concentration sensor, screen, battery, main control circuit, and buttons. Input and ou...
