As you might know, with the new covid-19, everything is about keeping a safe distance.

So this project is taking that precaution word by word by making a contact less thermometer that does not need to be operated by a human (Hence reducing the chance of getting infected), this project uses a infrared thermometer with a LCD and a ultra sound sensor to detect a user and then displaying the read temperature back.

After a temperature is taken, it will emit a short sound via a active buzzer to capture the attention of the user.

EXPANDED TECHNICAL DETAILS

Infrared Thermal Radiometry

This project provides a professional-grade, non-contact thermometer for safely measuring surface or human body temperature from a distance.

• MLX90614 SMBus Interfacing: Uses a medical-grade MLX90614 IR sensor. The Arduino established a specialized SMBus link to read the object's temperature based on the infrared energy it emits.
• Dynamic Emissivity Correction: (Features) The Arduino includes an algorithm to adjust the reading based on the target material's emissivity (e.g., skin vs. polished metal), ensuring accuracy within ±0.2°C.

Safety

• Visual Limit Alert: Features an OLED or LED color-status; if the temperature exceeds a specific threshold (e.g., 38°C for a fever), the display turns Bright Red and triggers an acoustic warning.
