This paper proposes a new accessible design of entrance guard system based on the infrared sending and wireless signal control. The design can have access to the entrance guard system without swiping any cards or touching any devices. The system consists mainly of the sensing and control module, and the responder module. We build up the wireless transceiver based on the IC module NRF905, and analyze the principle of the circuit of infrared identification, as well as that of the wireless communication of NRF905. The result shows that this design is simpler, reasonable and practical. The sample product of the system（demo version） also demonstrates its reliability and low energy consumption, which further confirms that the proposed system can meet practical requirements and have good potential for future market application.
