Classification of Sensors

Classification of Sensors

Several classifications for omron sensors are rendered by various writers and experts. Some are very straightforward and others are quite nuanced. A topic specialist can also be able to use the following classification of sensors so this is a very basic classification of sensors.

These are categorized within the first category of sensors, active and passive. Active sensors are those which need an external light signal or a control signal. Passive sensors on the other hand require no external power signal and have a direct response to the output.

The other classification method concentrates on the sensor detection system used. Requires physical, biological, radioactive, radiation and other detection techniques. The following differentiation centres on the phenomenon of input and output conversion. Some of the typical phenomena are photoelectric, thermoelectric, electrochemical, electromagnetic, thermo-optic and etc.

The sensors are the final classification of both analog and digital sensors. The analog sensors produce an analog display, i.e. a constant output signal, in terms of the measuring distance. In comparison to the analog sensors, digital sensors operate with isolated or physical data. Data used in automated sensors for analysis and transmission are of a physical type.

Different Types of Sensors

Below is a collection of the various styles of sensors that are widely used for specific applications. These sensors are also used to measure physical properties such as temperature, resistance, strength, conduction, transmission of heat and etc.
· Climate Sensor
· Concurrence Sensor
· Accelerometer
· IR Sensor (Cardinal Sensor)
· Compressing Sensor
· Radiation Sensor
· Ultrasonic Sensor
· Smoke, Gas and Alcohol Sensor
· Contact Sensor
· Colour Sensor
· Moisture Sensor
· Tilt Sensor
· Flow and Level Sensor


In a nutshell, current sensor development tends to increase the versatility of sensor products. Together with the new electronic technologies, the higher versatility and reduced manufacturing costs enable computer processing on a microelectronic device that previously required large and complex signal processing systems such as transduction, signal amplification, filtering and other processing on smart sensors. From an end-user point of view, the sensor device now seems clearer, despite its improved flexibility and internal sophistication.
