Abstract—Pyroelectric sensors are the most suitable for detecting human motions because they are sensitive to human motions induced variances in the infrared radiation. A pyroelectric sensor array is designed and used to build an event-time sequence in an infrared radiation domain. Then, the sequence is used to contrast with a password sequence for further recognizing human hand motions. This is applied on the intelligent life for controlling doors to open or close as a pyroelectric lock. For estimating the functions of the pyroelectric lock, six password sequences are used to control the proposed device via discreet manipulation of six persons. The experimental results verify the feasibility and efficacy of the proposed design. The false recognition is lower than 2%.
