【 摘 要 】

Nowadays, the pressure controller is one of the most commonly used sensors in the market, it has advantages of good real-time performance, good efficiency, but also exist precision is poor, low resolution and volume weight, inconvenient to carry shortcomings. Therefore, this article designed a high accuracy pressure controller based on zigbee transmission, and gives the design diagram, hardware composition and software system, the system USES 51 single chip microcomputer, ten high precision A/D conversion chip HX711, cantilever type resistance strain sensor and zigbee wireless transmission module, system can be collected in real-time and high precision gravity through to the digital tube display;, at the same time, through the zigbee wireless transmission way of transmitting current data terminal equipment (such as: PC, mobile phone, etc.), convenient for the user in the long-distance real-time view the latest data, in improving the efficiency of using the system at the same time, also ensure the data real-time and efficiency.
