Abstract: This work presents the design and practical implementation of an embedded system which can measure temperature of the environment and uses an ultrasonic sensor to measure the distance of objects ranging from 2 cm to 400 cm. The measured temperature is compensated to find the speed of the ultrasonic wave to obtain a more accurate distance measurement. The heart of the embedded system is a low-cost, low-power, and high-performance ATmega328P microcontroller from Atmel. The results showed that, using the TMP36 for temperature compensation improves the accuracy of the designed system.
Keywords: Distance measurement, embedded system, microcontroller, temperature sensor, ultrasonic sensor.
