发明名称 Device for simulating human activity in an unoccupied dwelling
摘要 The present invention is a thermally activated electrical switch for use in simulating human activity. The invention is features dual heat sources enclosed in a thermally isolated chamber within the invention. Since the activation of the switch is dependent upon the ambient temperature of the environment, it opens and closes at sufficiently random intervals to simulate human activity. This embodiment includes the use of a photoelectric sensor to further vary timing of the switch actuation.
