The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.
scope of operation research
The preventive maintenance system ensures the safe operation of equipment.

The Boiler operation engineer exam information can be found by contacting the nearest state boiler and labor director office for details. When he state and government decide to announce the information is available.

Inverse piezo-electric effect.
Ultrasonic sensors are used as animal repellents. There are some sensors that are designed to only genereate ultrasound when an animal is detected with the motion sensor.
There are many types of level sensors you can use to measure the water level in a tank such as submersible level sensor, ultrasonic level sensor, float level sensor. If you are searching for a level sensor you visit our website iconprocon[dot]com
principle refers to the basic objective of something. Operation refers to how it operates.
It is a motion detector that detects motion using sound waves
Any Sensor has to have an electrical connection to transmit signals from the sensor the the VDU. however it is a DC connection varying in Voltages between 24 and 120V, and current would be 4 to 20 mA
It is a motion detector that detects motion using sound waves
used to find distance between moving or stationary object
piezo electric principle
There is the main robotics brick, four wheels, two balls, ultrasonic sound sensor, touch sensor, light sensor, sound sensor, cables, and many other bricks
two types one is ultrasonic and other is ir sensors
Many - fish finders, many sonar devices.
