Provided is a charging portable wireless gas monitoring terminal, utilizing a single-unit lithium battery as an electric energy memory, possessing a USB charging mode and a solar energy charging mode, and employing an MCU as a control core. The gas monitoring terminal can be used as a portable device to be arranged indoors or outdoors or at other places requiring monitoring, and can be in connection with a USB charging cooperation lithium battery for use indoors, and in connection with a solar panel charging cooperation lithium battery for use outdoors. The charging portable wireless gas monitoring terminal can directly display collected data values on an equipment LED, and also can be used as a ZigBee terminal device to send data to a ZigBee coordinator node through a ZigBee protocol, thereby realizing the function of remote monitoring. The charging portable wireless gas monitoring terminal can be used as a hand-held monitoring terminal and a remote monitoring terminal, and has the characteristics of small size, light weight, portability and low power consumption.
Description
technical field [0001] The invention relates to the field of air quality monitoring, in particular to a rechargeable portable wireless gas monitoring terminal. Background technique [0002] Air quality is an indispensable content in environmental monitoring. At present, the commonly used air monitoring system can be installed in a fixed position to effectively monitor the concentration of main pollutant gases in the air, with excellent performance. However, the biggest problem with this type of air monitoring system is that the system is very large and requires wiring to transmit data, which takes up space; the power consumption is large, which increases energy consumption; the weight is also large, and it is not convenient for mobile monitoring; Imports are expensive and increase the cost of use. [0003] Therefore, the present invention completes a rechargeable portable wireless gas monitoring terminal. Contents of the invention [0004] The purpose of the present inve...
