Title:
PYROELECTRIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/034149
Kind Code:
A1
Abstract:
Provided is a pyroelectric sensor, comprising a base (11), a tube cap (12) covering the base (11), a sensing element (13) arranged in the tube cap (12), and a lead (14) provided at the base (11) and with one end connected to the sensing element (13). An accommodating cavity for accommodating the sensing element (13) is formed between the base (11) and the tube cap (12). The sensing element (13) is arranged inside the accommodating cavity. The shape of the tube cap (12) and/or the base (11) corresponds to that of the sensing element (13) so as to equalize heat conduction from the tube cap (12) and/or the base (11) to the sensing element (13), so that noise sensed by the sensing element (13) is substantially uniform, thus facilitating subsequent denoising and facilitating direct signal output. The pyroelectric sensor has the advantages of high production efficiency, low production cost, and good mechanical performance.
