Definitions
- the invention relates to a USB rechargeable ZigBee network wireless air pressure sensor, belonging to the ZigBee network wireless air pressure sensor innovation technology.
- Conventional air pressure measuring devices generally use mechanical barometers for direct measurement or single sensor measurements. Data acquisition is done by manual field readings. Mechanical barometer measurements are simple, but require a lot of labor and poor real-time performance in the data acquisition process. Human error is also prone to occur; when there is a large amount of air pressure on the site (such as a large number of airbags in the airbag construction technology), it takes a lot of time to read all the air pressure data.
- the wireless air pressure sensor network based on the ZigBee network mode can measure the air pressure of multiple measuring points and collect the air pressure data of each air pressure point through the ZigBee coordinator, and then display it through the PC interface, or through the network protocol converter.
