IR Sensor vs. Ultrasonic Sensor: What is the difference ...

· Applications for Ultrasonic Sensors Mobile Robot Object Avoidance. Ultrasonic sensors are often used on mobile robots to avoid objects. You can use an array of HC-SR04 sensors and determine which way to move depending on which sensor has the highest distance reading. This will tell you that objects are farther away and it’s therefore, safer to move in that direction.

Infrared temperature sensor system for mobile devices ...

· An alternative for accurate environmental temperature measurement in mobile device application is infrared (IR) temperature sensing. IR sensing offers a non-contact method to measure the temperature of targets due to the fact that all objects whose temperature is above absolute zero emit IR radiation . The target temperature sensing is based on the measurement of the IR radiation emitted by …
