Non-contact type temperature sensing device with constant distance measurement and temperature measuring method thereof

摘要

A non-contact type temperature sensing device (10) includes an emitting unit (110), a detecting unit (120) and a single chip microprocessor (11). The emitting unit (110) emits a signal to a temperature-measured body. The detecting unit (120) receiving a reflected signal emitted by the emitting unit (110) and reflected by the temperature-measured body. The single chip microprocessor (11) is electrically connected to the emitting unit (110) and the detecting unit (120). The single chip microprocessor (11) determines a measuring distance between non-contact type temperature sensing device (11) and the temperature-measured body according to the reflected signal. When the measuring distance is located within a preset measuring range, the single chip microprocessor (11) outputs an enabling signal of measuring temperature.
