In the broadest definition, a sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor. A sensor is always used with other electronics . A sensor is defined as a device or a module that helps to detect any changes in physical quantity like pressure, force or electrical quantity like current or any other form of energy
A device that detects the changes in electrical or physical or other quantities and thereby produces an output as an acknowledgement of change in the quantity is called as a Sensor. Generally, this sensor output will be in the form of electrical or optical signal Second, the sensor's range may shift due the same conditions just noted, or perhaps the operating range of the process has changed. For example, a process may currently operate in the range of 0 to 200 pounds per square inch (PSI), but changes in operation will require it to run in the range of 0 to 500 pounds per square inch (PSI) Outline and detection principle. As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception An ultrasonic sensor is a type of electronic equipment that emits ultrasonic sound waves and converts the reflected sound into an electrical signal to determine the distance of a target item. Ultrasonic waves travel quicker than audible sound (i.e. the sound that humans can hear). The transmitter, which generates sound using piezoelectric.
Pressure sensors need to be calibrated so it knows what voltage or milliamp (mA) signal corresponds to what pressure. This is a basic Zero and Span calibration or minimum and maximum which is a common job for maintenance personnel There are many types of Gas sensors but the MQ type gas sensors are commonly used and widely popular so will focus more on these types of sensors for this article. Introduction to Gas Sensor. A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage
A Hall effect sensor is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect.

Occupancy sensors may offer an option selection to switch the occupancy sensor from automatically turning the lighting on to A vacancy sensor requires manual activation of the lighting by the occupant then turns the lights OFF automatically soon after an area is vacated. A vacancy sensor does not offer an option of automatically turning. A pressure sensor works by converting pressure into an analogue electrical signal. The demand for pressure measuring instruments increased during the steam age. When pressure sensing technologies were first manufactured they were mechanical and used Bourdon tube gauges to move a needle and give a visual indication of pressure Each sensor is made up of individual picture elements, or pixels, which are laid out in a matrix design. For each pixel, there's a lens in front, sensors in the back, and wires somewhere in the middle.
