Design of Rechargeable Air Pressure Sensor Based on ZigBee Wireless Network Technology

摘要

We have made some improvements in the design of its new generation for the first generation of the wireless pressure sensor that has been successfully used [1][2]. The sensor is mainly applied for monitoring air pressure of airbag during the process of operating the ship. As for the design of sensor circuit, TI BQ24072 charge management chips are used to realize online charging, so sensors can work continuously and meet the needs of the construction site. And experiments show that the improved pressure sensors work stably and get the charging function.
