Embodiment Construction
[0015] Below in conjunction with specific embodiment and accompanying drawing, the present invention is further elaborated and illustrated: please refer to figure 1 , 2 , a pyroelectric sensor, comprising a cap 10, a base 20, the cap 10 is mounted on the base 20, a cavity is formed between the cap 10 and the base 20, the An induction element 50 is arranged in the cavity.
[0016] The base 20 is provided with a set of pins 40, one end of the set of pins 40 protrudes into the cavity, and the top end of the set of pins 40 protruding into the cavity supports an induction element 50, the The pin set 40 is connected to the sensing element 50 through silver paste, and the other end of the pin set 40 protrudes from the bottom of the base 20 to transmit signals to external devices. The direct connection between the pin group 40 and the induction element 50 reduces the interference of the intermediate circuit, and the thermal field of the product is more stable.
[0017] The sensing ...

The invention discloses a pyroelectric sensor. The pyroelectric sensor comprises a pipe cap and a pedestal, wherein the pipe cap is arranged on the pedestal; an optical filter is arranged at the top of the pipe cap; a pin set is arranged on the pedestal; the pin set supports an induction element; the induction element includes a receiving module and an output module; the receiving module is used for receiving an infrared optical signal which is filtered by the optical filter and converting the infrared optical signal into a voltage signal; the output terminal of the receiving module is connected with the input terminal of the output module; the output module and the pin set are connected through silver paste; and the output module transmits the voltage signal transmitted from the receivingmodule to the outside from the pin set. The pyroelectric sensor can improve the anti-interference capability and save the packaging cost by directly outputting the voltage signal through the induction element.
