Non-contact infrared temperature detection and RFID technology access control design

Abstract The non-contact infrared body temperature detection and RFID technology access control design uses 51 single-chip microcomputer as the core main control module, which combines infrared temperature measurement function (GY-MLX90614 sensor) and radio frequency (MFRC522) card swipe access control system, through swiping card and temperature measurement together control the door opening and closing. When it works in the high-risk zone mode, it detects the body temperature while swiping the card. If the body temperature is normal, the door opens, if the body temperature is abnormal, the door does not open and the buzzer sounds; when working in the low-risk mode, if the body temperature is normal, the door opens, If the body temperature is abnormal, the door opens and the buzzer sounds. Finally, it inputs the obtained card information and body temperature data to the WiFi circuit (ESP8266) through the serial port, and uses it as a hotspot to connect to the mobile device to realize data transmission, so as to realize more efficient unmanned management in different areas during the epidemic.
