9 Common Types of Sensors in Various Digital Industries

jenis jenis sensor

The digital industry is experiencing rapid development today. Almost all equipment and systems use digital mode in them so that they can operate properly. The use of sensors cannot be separated from every digital device and system so

that they are able to detect and measure various parameters and changes in their surroundings. The question is, what are the types of sensors used in the digital industry today?

Definition

By definition, a sensor is a device capable of detecting changes in physical quantities such as force, pressure, motion, light, temperature, humidity, speed, electrical quantities, and other phenomena.

Sensors work by converting physical or chemical signals into electrical signals that can be processed by computers or other devices. The sensor is connected to a device called a transducer.

The transducer converts physical or chemical signals into electrical signals, then sends these signals to a microcontroller or computer for further analysis. In essence, sensors play an important role in collecting data that can be processed to produce useful information.

Functions

Sensors have various functions in the digital industry. Its main function is to detect, measure and monitor certain parameters in the surrounding environment.

The data collected by these sensors can be used to control and regulate various automated systems, and provide important information for decision making.

In the digital industry, sensors are often used to monitor temperature, light, motion, magnetism, sound, infrared, pressure, and even biometric characteristics. Sensors create systems that are more efficient and safer to use.

Types in the Digital Industries

There are nine types of sensors commonly used in the digital industry, ranging from light sensors which are commonly used to biometric sensors which are the latest technology.

1. Light Sensor

First, there is a light sensor that is used to detect and measure the light level around it. In the digital industry, these sensors are used in automatic lighting settings in office buildings or smart homes.

Light sensors can detect changes in light and send signals to the control system to adjust lighting as needed.

An example Is an automatic lighting system in a meeting room. When the light sensor detects a decrease in light levels due to the presence of people in the room, the lighting system automatically turns on the lights thereby saving energy and providing comfort to room users.

2. Electric Sensor

As the term implies, electrical sensors are used to detect electric current or voltage in a circuit. Electrical sensors are also useful in measuring energy consumption and monitoring the performance of electrical equipment.

An example is the measurement of electric power in a household. Electrical sensors installed in the electrical panel work by detecting the electric current used by various household appliances.

The data collected is used to monitor and manage energy use and identify energy-intensive equipment.

3. Motion Sensors

Motion sensors are used to detect any movement or change in position. These sensors are often used in various applications in the digital industry, such as security systems, automatic control, or even in gaming devices.

An example is a home security system that works by detecting movement around the house. If any movement is detected, the alarm system will be activated, and the home owner will be notified via a notification on his smartphone.

4. Magnetic Sensors

Next, there is a magnetic sensor that works by detecting the magnetic field around it. In the digital industry, magnetic sensors are used in digital compasses, position sensors or in magnetic data recording devices.

An example is in car navigation, where a magnetic sensor built into a vehicle can detect changes in the magnetic field caused by a change in the vehicle’s direction. This data is used to determine the correct direction and assist the driver in navigation.

5. Temperature Sensor

The temperature sensor is used to measure changes in the surrounding temperature. These sensors are especially important in digital industries, such as refrigeration systems, temperature monitoring in factories, or medical devices.

An example Is a temperature sensor installed in a room that can detect an increase in temperature and sends a signal to the cooling system to turn on or turn off the air conditioner as needed so that the temperature remains comfortable.

6. Sound Sensor

The sound sensor or microphone functions to detect and measure the sound around it. In the digital industry, these sensors are used in speech recognition systems, communication devices, or in audio devices.

An example Is the use of virtual assistants on smartphones. The built-in voice sensor detects the user’s voice and activates the virtual assistant to respond accordingly.

7. Infrared Sensor

Infrared sensors are used to detect infrared radiation rays that are invisible to the human eye. Its implementation in the digital industry includes temperature control systems, motion detection, or in infrared camera devices.

An example is the temperature control system in electronic devices. The infrared sensor works by detecting the user’s body temperature and sending a signal to the temperature control system to adjust the output temperature according to needs.

8. Pressure Sensor

Next, there is a pressure sensor that works by measuring the pressure of the surrounding gas or liquid. These sensors are often used in barometric pressure measurement systems, pressure measurement in hydraulic systems, or in medical devices.

An example is a tire pressure measurement system on a vehicle that can detect changes in pressure and provide information about the appropriate tire pressure so that vehicle safety and performance are maintained.

9. Biometric Sensor

Finally, there are biometric sensors that are useful in recognizing and measuring a person’s biological characteristics, such as fingerprints, faces or irises. These sensors are gaining popularity in the digital industry and are applied to biometric recognition systems, data security or door locking devices.

In the digital industry, biometric sensors are also used for mobile applications in the financial sector to increase application security.

For example, using face recognition to authenticate and verify users who are using a financial application for the first time. The biometric sensor system used must have a high level of security.
