The invention discloses a health code reading and temperature measuring auxiliary device and method. The device comprises a shell, a working state panel arranged on the surface of the shell, and a microprocessor, a health code scanning device, a loudspeaker, an automatic temperature sensing device, a laser sensor, a human body sensor, a storage unit and a wireless communication unit which are arranged in an inner cavity of the shell. The input end of the microprocessor is connected with the health code scanning device, the automatic temperature sensing device, the laser sensor and the human body sensor, and the output end of the microprocessor is connected with the working state panel, the loudspeaker, the storage unit and the wireless communication unit. The shell is further provided with a two-dimensional code scanning cavity, an automatic temperature sensing device probe hole, a laser sensor probe hole, a human body sensor probe hole and a horn hole. The device simulates entrance and exit on-duty personnel, automatically finds personnel approaching, prompts temperature measurement bright codes through voice, prompts the on-duty personnel to pay attention to personnel operation and verification results, and realizes a working mode of automatic working of the device and real-time supervision of the on-duty personnel.
