vibration sensor are many type but i am sharing with you only accelerometer vibration sensor meter
Working principle: measure the rate at which the velocity of an the object is changing
Note: acceleration can,t measure directly and accelerometer measure the force exerted by restraints that are the fixed spot or place
Newton @and law apply here: mass* acceleration

Sensors are designed to respond to a particular change in condition. Pressure, temperature, barometric, rainfall and so on.
Usually they take the form of a transducer to convert the signal into an electrical one, which makes subsequent manipulations easy.
The specific answer to your question depends on the specific sensor you are referring to.
In general, a sensor of some sort (pressure, flow, light, current, voltage, motion/occupancy, temperature) is put in series with the load it controls. It can be normally open (NO) or normally closed (NC).
If NO, once the sensor "senses" what it is meant to react to, it will close the circuit and the load it controls will turn on.
If NC, the circuit will be opened and the load will turn off.
it is a transducer which gather data and convert it to voltage equivalents
Many digital sensors are just an analog sensor with an ADC and some type of digital interface connected to it so that the reading can be transferred as a digital number.
explain
the bms system is working through the logic created and controlled by the controller and the sensors based on the return air sensor in hvac bms system
based on the pizoelectric effect. Change in resistance due to the force acting on it and convert it into 4 - 20 mA.
If it's PIR (that's passive infra-red) then think of it as an eye that can only see changes in heat, staring straight forward. Whenever something that's warmer or colder than the background moves in or out of its field-of-vision, the sensor reacts to this change in scenery and trips an alarm.

A simple test to know if the car computer is working.?æ Identify your sensor and turn on the ignition to see if the sensor confirms the car's computer.
how to tell if my crankshaft sensor is not working
Speed Sensor is not working
if it does not work
How to know if air sensor not working on protege 2003
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
how do you check the abs sensor on a 1998 contour
Oxygen sensor slow response. It means the sensor is worn out and working slowly
It is the downstream sensor on one side of the engine that tells the computer how well the catalytic converters are working.
My auto lamp light sensor is not working on my Mercury Sable 2002. Why?
possibly, the speed sensor
