Contact less infrared based thermometer with MLX90614, DHT11, Arduino, Oled

A contactless infrared thermometer using the MLX90614 sensor, DHT11 sensor, Arduino, and an OLED display offers a practical solution for non-invasive temperature measurement. The MLX90614 is a high-precision infrared sensor that can measure the temperature of an object without direct contact, making it ideal for applications where hygiene is a priority, such as in medical settings. In this setup, the MLX90614 sensor measures the surface temperature of an object or person from a distance, typically a few centimeters. The DHT11 sensor, known for its reliability in measuring ambient temperature and humidity, complements the system by providing environmental data. These readings help adjust the infrared measurements, ensuring accuracy by accounting for the surrounding conditions. The Arduino microcontroller serves as the brain of the system, processing data from the MLX90614 and DHT11 sensors. It then sends this data to an OLED display, which presents the temperature readings in a clear and concise manner. The use of an OLED display is advantageous due to its low power consumption and high contrast, making it easy to read in various lighting conditions. This combination of sensors and components creates a robust, contactless thermometer that is not only accurate but also easy to use. Such a device can be particularly useful in scenarios requiring frequent temperature checks, such as during health screenings or in industrial environments, where maintaining cleanliness and reducing the risk of contamination are critical.
