The utility model provides a gesture identification device, including the gesture recognition ware there are first switch element, pyroelectric sensor and thalposis circuit, first switch element set up in between gesture recognition ware and the power, pyroelectric sensor is used for detecting near biological heat source, when there is biological heat source in near, and output the first signal, the thalposis circuit includes temperature sensor for sensing temperature, and output sample voltage, master module for provide a reference voltage, relatively the module is coupled in master module and temperature sensor, when sample voltage is greater than reference voltage, and the output second signal, first switch element is received simultaneously the first signal with it is closed during the second signal. Be in standby state, and the pyroelectric sensor of low -power consumption and temperature sensor work, when the human body was close to, two sensors were then judged to get into the target area with responding occasionally, the work of gesture recognition ware is comparatively simple equitable, practices thrift the electric quantity.
