Color Sensor

Color sensor is a sensor that is used to detect the color of an object.

This color sensor as actually a photo electric sensor that has a special character combination of color red (R) green (G) and blue (B). For that reason, color sensor often called the RGB color sensor. 

Floatless Sensor

Floatless sensor or Floatless switch is the sensor to detect level of liquid which is detected through electrodes submerged in the liquid.

Proximity Sensor

Proximity Sensor is a sensor to detect the object without touching the object being detected. The detected object can be either metal and non metal.

Temperature sensor

Temperature sensor is a sensor to detect the temperature of an object or room. 

Temperature sensors are very widely used both in industry and daily life due to temperature or thermal parameters are very influential in the process.

Encoder for Position Detection

Rotary Encoder is a sensor or device for detecting the direction of rotation, the angle position, and rotational position. 

Limit switch sensor

Limit switch sensor is one of the earliest type of sensor that work mechanically. This sensor basically a switch that can be in a state of ON or OFF as a result of mechanical movement.

Limit switches are basically formed from basic switch are then packaged in single unit to be used in accordance with particular application.

Pressure Sensor

Pressure sensor is the sensor to detect the pressure both positive pressure and negative pressure.Positive pressure is pressurized air generated by the compressor, while the negative pressure or vacuum is generated by air suction vacuum pump.

Photo Electric Sensor

Referring the definition of photo electric sensor that has been described previously, Photo electric sensor is the sensor that detect the object by transmitting a beam with intensity that has been determined. The beam can be infra red or photo electric. All object can be detected by these sensors, because the sensor detects the light emitted by the object being detected.

Type of Sensors in Automation

Sensors is a device used to detect an object, and the result of the detection variable will be processed into an output signal of digital status (ON-OFF) or analog signal.
There are many sensors maker such as Omron, Keyence, Fuji, Siemans, Allan Bradley and so on. The following image is an example of sensor made by Omron:
