Sensors: Making Our Life Easier

Maybe you are curious about how sensors work.

How important it is in so many things.

How helpful sensors can be in our life.

Sensors in today’s world…

In our modern world, we use a lot of devices. Everything is becoming automated now and making our life much easier. How?

Industries today are using high-quality instrumentation, sensors for automation, machine safety and connectivity products. This is to make their production and operation much easier and faster.

Sensors for automation are a great example of how a sensor makes our life much easier.


A sensor is a device that detects and responds to an input. It converts the input into data that the computer can process. There are different types of input that a sensor can convert.

Sensors: Input Type

• Light
• Heat
• Motion
• Moisture
• Pressure
• Water Level
• Proximity
• Switch

On the other hand, the output is a signal converted in a way the human can understand. The output will show on the computer screen. There are a lot of sensors in many types.

Types of Sensors

Temperature Sensors
    - It collects the information about temperature.
IR Sensor (Infrared Sensor)
    - It detects infrared radiation to sense a particular phase in the environment.
UV Sensor
    - It measures the intensity of the ultraviolet radiation.
Touch Sensor
    - Acts as a variable resistor as per the position where it is touch.
Proximity Sensor
   - It detects the presence of objects that place without any point of contact.
• Accelerometer
   -It detects whether your phone is in portrait or landscape orientation.      
• Pressure Sensor
   - It measures gases or liquids.    
• Light Sensor
   - It detects light density.
• Ultrasonic Sensor
   - It detects the presence of a target object.
• Smoke, Gas and Alcohol Sensor
   - It detects smoke, gas, and alcohol.
Color Sensor.
   - It detects color.
• Humidity Sensor
   - It measures and reports the moisture and air temperature.
• Tilt Sensor
   - It detects orientation.
• Flow and Level Sensor
   - It detects the level of substances that can flow like a liquid.

Sensors are very helpful to us. As technology continues to advance and developed, a lot of tasks are becoming more automated and advance as well. There are of ways where you can use sensors for different purposes.

Purposes of sensors

1. Data collection from environment

Sensors used to collect data from our environment.

A good example of this is to know the water level when there is a big chance of flooding in some areas.
The authorities can monitor the level of flooding even if they are not in the area. With this monitoring, they will know when the best time to evacuate is. With the help of a sensor that detects the water level, it helps to save our lives.

2. Smoke Prevention

Aside from collecting data from the environment, sensors also help to detect smoke, especially in buildings and houses. This type of sensor is a smoke sensor.

When there a smoke is being detected by the sensor, there will be a fire alarm. Everyone inside the building can leave the building as soon as they hear the alarm.

3. Adds Security

Homes nowadays are becoming smarter and smarter. With the advancement of technology, the internet of things makes our life much easier.

A motion sensor is one of the great examples of sensor that helps your life more convenient and easier.

Usually, smart homes today are using smart doorbells or doorbell sensor. It starts playing a live video when someone is standing in the doorbell area. This smart doorbell alerts you if there is a person standing in your door, even if the doorbell is not being pressed yet.

Aside from that, motion sensors and other types of sensors are more utilized in the industries. It makes the industrial production easier, safer, and faster as sensors can do simultaneous work. Below are the common sensors that are usually used in our industries today:

Common Used Sensors in the Industry

• Inductive Proximity Sensors
• Capacitive Proximity Sensors
• Photoelectric Sensors
• Flow Switches
• Pressure Sensors and Gauges
• Laser Distance Sensors
• Safety Light Curtain
• Rotary Encoders
• Linear Encoders
• Thermocouples

Sensors make things easier for us. By turning switches, things work. It benefits everyone like businesses factories to help them to measures things. We use our senses in our everyday living. And we use sensors to extend what human cannot do.
