Sense IoT's Ultrasonic Sensors can be used in a variety of applications for measuring distances between the sensor and objects in its path. Ultrasonic sensors are imperviousness to target surface and color, and feature auto calibration 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 Sense IoT 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 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), the other receives them, (like a tiny microphone). The ultrasonic sensor uses the speed of sound to time the 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 Sense IoT 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.
