RFID (radio frequency identification) chips are usually called electronic volume label or radio frequency volume label. Now a new transponder is developed and it can accurately measure the surroundings pressure, temperature and humidity. Besides, it can complete the function of sensor by combining with RFID chips, which make the transponder can monitor the change of pressure, temperature and humidity and this information can be sent to reading device through RFID chip. This paper combines this technology and fire alarm system to prevent fires. This system connects RFID chips CC2430 sensor with each temperature sensor DS18b20. DS18b20 is placed in the area needed to be monitored according to certain order, and the single way is employed to connect every CC2430 module. The temperature sensor DS18b20 and its connection with CC2430 chips hardware are very practical and simple. We combine its address line, control line, and data line into one signal line which can be controlled individually and just needs CC2430 1 root I/O lines.

This paper describes the development of a two-factor radio frequency identification (RFID)-based security door authentication scheme that can provide efficient control facilities to restrict the entry of an unauthorised door user. The developed system consists of the RFID unit, a microcontroller programmed to control the operation of the door using a synchronous motor. The multiplexers that comprise integrated circuits combined with the liquid crystal display was utilized for displaying the status of the card user while the alarm system informs the public of an intruder. The experimental results are presented and discussed.
