Study Notes
Ultrasonic Technology
- Ultrasonic transmitters generate high-frequency sound waves to measure speed or direction.
- Measuring speed or direction using ultrasonic technology is used to detect object movement or distance.
Ultrasonic Receivers
- Ultrasonic receivers detect the reflected sound waves and convert them into electrical signals.
Ultrasonic Transducers
- Transducers are used to generate sound waves in the range of 20 kHz to 40 kHz.
- A transducer is an example of a device that converts one form of energy into another.
Sensors
- The primary function of a sensor is to detect and respond to various inputs.
- Examples of inputs that sensors can detect and respond to include temperature, light, and sound.
Transduction in Sensors
- Transduction in the context of sensors refers to the process of converting one form of energy into another.
- The role of a transducer in the context of sensors is to convert the detected input into an electrical signal.
