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

05/10/2019· 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.

What is an Ultrasonic Sensor? | FierceElectronics

07/10/2019· An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Ultrasonic waves travel faster than the speed of audible sound ( the sound that humans can hear). Ultrasonic sensors have two main components: the transmitter (which emits the sound using …

Ultrasonic and Passive Infrared Sensor Integration for ...

Ultrasonic sensors do not have gaps in the coverage zone like a PIR sensor and can be sensitive to slight motions at nearly twice the distance. The overall detection range is comparable to that of a PIR sensor. The ultrasonic sensor also can detect motion behind partial obstructions. One of the key advantages of the ultrasonic sensor is the ability to calculate distance to the object in motion.

PIR Sensor: Overview, Applications and Projects - Latest ...

03/08/2019· PIR sensors are commonly used in security alarms and automatic lighting applications. Technically, PIR is made of a pyroelectric sensor, which is able to detect different levels of infrared radiation. For example, Everything emits varied level radiation and the level of radiation will increase with the increase of the object’s temperature.

Occupancy Sensors: Passive Infrared, Ultrasonic and Dual ...

01/09/2008· PIR sensors require a direct line of sight between the sensor and occupants in a space. Because of this requirement, managers can strictly define the sensor’s coverage. Ultrasonic sensors cover the entire space and do not need a line of sight. As a result, they can detect people behind obstacles. They also are more sensitive to minor motions, such as hand movements.
