11This   Sketch is for a contactless, automatic temperature reader to avoid human contact,
12in   a effort to reduce covid-19 contaminations.
13This works using the MLX90614 sensor   to accurately measure body temperature.
14
15-it also uses a 16x2 LCD display
16-a   HC-SR04 Ultrasonic Sensor
17
18the project uses a ultra sound sensor to detect   the distance between,
19the user and the sensor, if this distance is within the   specified limits,
20the reading will start after a 10 milliseconds delay,the temperature
21will   then be display in lcd and 3 short sound will be made by a active
22buzzer to catch   the attention of the reader to lcd screen
