Digital Sensors and Sensor Sysstems


Abstract: This article presents a low cost, 2-channel, accurate ultrasonic sensor system based on smart HRLV-MaxSonar – EZ Series MB1013 ultrasonic sensor, HR-MaxTemp temperature sensor and Universal Sensors and Transducers Interface (USTI) integrated circuit. The experimental investigations have confirmed high metrological performances of the designed sensor system. It was shown that the quantization error of pulse width-to-digital conversion can be neglected in comparison with the sensor’s error because of it is in 2-3 orders less than the sensor’s error. Due to the high metrological performances and technical characteristics the developed ultrasonic sensor system can be used for any frequency-time parameters output (pulse width, frequency, PWM, etc.) ultrasonic sensors, existing on the modern market. The similar systems with the same metrological performances can be easily build also based on USTI-EXT, USTI-MOB, UFDC-1 and UFDC-1M-16 integrated circuits. The proposed sensor system is well suitable for such application as distance measurements; tank level measurements; objects, people and vehicle detections and monitoring; garage parking assistants; motion detectors, etc.


Keywords: Distance measuring system, Ultrasonic sensors, smart sensors, Universal Sensors and Transducers Interface (USTI), UFDC-1, HRLV-MaxSonar, MB1013, HR-MaxTemp sensor.
