Data Acquisition & Logging

ALTA Ultrasonic Sensors can be used in a variety of applications for measuring distances between the sensor and objects in its path. ALTA ultrasonic sensors are imperviousness to target surface and colour, and feature autocalibration algorithms which allow them to adapt to variable environmental conditions and compensate for temperature and humidity effects. The ultrasonic sensors can also be calibrated through the iMonnit software for greater accuracy in distance measurements.

• Measures distance between the sensor and objects in its path

• Measurement resolution of 1 centimeter

• Auto-calibration algorithms allow sensor to adapt to variable environmental conditions

Principle of Operation

The Ultrasonic Sensor sends out a high-frequency sound pulse and then times how long it takes for the echo of the sound to reflect back. The sensor has 2 openings on its front. One opening transmits ultrasonic waves, (like a tiny speaker), and the other receives them, (like a tiny microphone). The ultrasonic sensor uses the speed of sound to and time difference between sending and receiving the sound pulse to determine the distance to an object. It will take readings at set intervals and report the data back to the iMonnit software portal where the information is processed to display distance and alert users if a defined condition is met. All sensor data is then stored for historical analysis.
