Story

Summery

We have presented a automated temperature scanning gate for monitoring the temperature of human when they passed trough the gate. if temperature of a person is more than 99 degree Fahrenheit then the gate automatically rejects the entry (by closing it). The gate also provides warning beeps if the temperature is high.

Manual temperature monitoring system

Description

The main objective of the system (temperature scanning gate) is to monitor the human body temperature when a they passed through the gate. In normal situation the gate is always open. If the gate senses any high temperature (more than 99.0 degree Fahrenheit), the gates automatically rejects the entry by closing the gate. The gate also provides warning beeps while the body temperature of a person is high.

Our world is effected by covid-19. Some health measurements are needed for preventing the covid-19 spreads. One of the early symptoms of covid-19 is high body temperature or fever. Our temperature monitoring gates able to detects high body temperature.

This temperature screening gate is useful for bus stops, hospitals, restaurants, airports, grocery stores and shopping malls etc. The implementation cost of this gate is also cheap (compare with heat camera). Thermal cameras are also used to monitor the temperature.

*During the demonstration we used Arduino Uno micro-controller.

We made the prototype gate using PVC sheets. We have installed a temperature sensor in the middle position at the top of the gate. The micro-controller and warning buzzer were placed next to the gate. The opening and blocking operation of the gate is performed by a servo motor.

  Serial.println("*F");
  Serial.println();

  delay(500);
