What are sensors?

Sensors are electrical devices that take in data about their surroundings, process it, and provide an output based on their input. This allows sensors to measure the world around them in a wide variety of applications, including robotics sensors to detect obstacles, automotive sensors to measure engine speed for car-cruise control systems, sensors used in home automation to turn lights on when someone enters a room or sensors that detect temperature. For most sensors, it is important to use the right sensors or parts of sensors with the most accurate material. This ensures they give out the right data which you need.

How do sensors work?

The information so collected by sensors is sent directly to the processor or CPU (central processing unit) where it is computed and turned into the desired result. For sensors to be able to send their data they need to be connected with wires/cables, Wi-Fi & Bluetooth mostly today. The sensors are either plugged into a slot on the motherboard or plugged into an external port like USB for example that directly makes them communicate with the Processor /CPU of the computer.

How are sensors used in homes or businesses?

Sensors are used in almost all sectors of business. This includes home sensors that can help by reducing energy consumption, for example, sensors that help monitor the temperature in the transport of goods or sensors that send out alerts when products need to be changed next. Other sensors are used for safety purposes, sensors on planes and cars that send out warnings if there is danger ahead (e.g., collision with another car).  Healthcare & life science use sensors mostly to monitor people’s health like their heart rates, oxygen levels, weight etc. There are even sensors used by Google Maps to make driving directions more accurate.  Further uses include factory settings where sensors detect whether machines need maintenance or how much they should produce per hour by counting the number of times they are used.

Sensors are used to help save energy with the use of smart meters. They also monitor electricity usage so you can see what appliances have been consuming how much power each month. Sensors are great for life-saving purposes as well, sensors on your smoke detector will go off if there is an abnormal rise in temperature which means there could be a fire or sensors that detect water levels to tell you whether it’s a flood or not.  Home sensors are also used for security purposes like sensors that detect motion to know whether somebody has entered your house, sensors that work kind of like cameras to record what’s happening inside your home & sensors that send alerts if someone opens certain doors you do not want them opening e.g., basement or garage however sensors are mostly used in homes to help with the health of the occupants.  These sensors include sensors that detect if somebody faints so you can be alerted & sensors on your fridge which send alerts when the food inside expires and needs to be replaced.

What are the benefits of using sensors?

Using sensors allows computer technology to evolve. Because sensors collect data and information from the surrounding environment, sensors help improve the processing speed, the accuracy and new technologies can be developed with sensors.  Sensors make your device and yourself safer and they also allow for new experiences.

Energy efficiency and security benefit of sensors

Today sensors play a major role in energy savings.  Sensors can be programmed to turn off devices when they’re not being used. Sensors enable the automation of tasks that would otherwise need human interference.  There are sensors that can sense absence or presence of people and adjust climate controls accordingly, sensors ensure comfort while saving power by switching off the lights behind you as you leave an area for example. They also make sure your appliances switch off if you forget them on which leads to energy savings automatically. With sensors, you can also save energy as sensors make your device more energy efficient.

Sensors also enable safety and security. Sensors make everyday tasks much easier and they protect our assets like homes, cars, devices from damages by detecting potential hazards before anything happens.  Sensors help improve quality of work, save costs & energy while making daily life stress free & more fun.

List of the most common types of sensors and their uses

  • Humidity sensors

Humidity sensors are sensors that measure the amount of water vapor in the surrounding environment.  Some humidity sensors can be used to monitor human breath which is useful in cases where people might not be able to breathe for themselves anymore and need external sensors like this one. Humidity sensors are useful in climate control, factories, dehumidifiers & machines like dishwashers among others.

  • Light sensors

Light sensors measure light intensity or luminosity.  They help computers take readouts from the surrounding environment and make decisions accordingly while ensuring energy efficiency.  Light detection sensors can also ensure safety by switching off automatically if there’s a lack of light e.g at time when you go out for a walk at night.

  • Temperature sensors

These sensors detect changes in temperature and can be used to monitor environmental temperatures or from physical objects that conduct heat like the human body for example.  Sensors of this kind are useful in climate control, factories & devices/machinery with a heating element among other things.

  • Magnetic sensors

These sensors measure magnetic fields around them which is very important in automation especially when it comes to machines that need a lot of movement. Also, sensors of this sort usually use an electromagnet which makes them more effective than sensors that don’t have electromagnets.  Magnetic sensors are ideal for robotic purposes such as sending robots into space where they’d be needed since unlike humans, they’re immune to the conditions in space.

  • Accelerometer sensors

Accelerometer sensors measure acceleration and vibrations in devices & equipment like smart phones, computers, vehicles among others.  Accelerometer sensors are extremely important in robotics because they help robots detect if there’s been an accident so that they can be programmed to stop moving immediately and switch off their engines. They’re also used in sports such as boxing where sensors collect information about speed & power of punches thrown by boxers for further analysis or to help technicians improve robotic equipment.

  • Pressure sensors

These sensors are useful in detecting pressure changes in fluids, gases & other liquids where sensors of this sort are used to monitor air pressure, water levels among other things.  Pressure sensors are not only useful in everyday life but also crucial in industries like oil refineries where they’re used to ensure safety by shutting down pumps when there’s too much pressure build up which can be dangerous. They’re also very important in internet cable management since sensors ensure that if a node on the cable breaks due to high tension, then the rest of the cable is automatically shut off so as not to cause any damage which might lead to more severe problems such as data loss.

  • Photo sensors

Photo sensors are sensors that measure light intensity using pixels to get the readouts.  They’re used in devices like DVD players, computer screens, sensors & photocopiers among others.  These sensors also use an electric current but in contrast to light sensors, photo sensors generate electricity when exposed to light which helps them collect data about its intensity by forming images on the sensor which each pixel representing a different level of luminosity.

  • Capacitive sensors

Capacitive sensors measure electrostatic discharges when they come into contact with an object.  They are used in sensors for touch-screens which adapt to the pressure applied to them by an object e.g finger thus allowing for accurate data collection.

Why should you invest in a sensor system today to make your life easier tomorrow?

We are living in a time where technology is quickly increasing and becoming more widely available to consumers.

Advances in sensors and sensor system technologies, such as miniaturization and low-power wireless connectivity, have made sensors a significant part of our daily life. The sensors monitor and measure environmental conditions. Sensors allow to collect information about the surroundings, process it in real time, act upon it to accomplish tasks that would be impossible by human means alone. Sensor technologies extend our five senses into a world beyond us where we cannot go individually with no robotic assistance. Devices are connected over the Internet and it can communicate with one another or receive instructions from afar. By utilizing such smart sensors powered by the cloud, many processes that used to require human intervention can now be automated. Sensors also enhance our healthcare. Sensors are even being developed that will respond to changes in body temperature and send alerts when individuals feel feverish or show other symptoms of severe illness.

Using sensors enables us to reduce the time it takes to make informed decisions. We also save money by using sensors in manufacturing processes: sensors determine where machinery needs servicing or maintenance, machines that need replacing or setting up, defective materials needing replacement at the early stages of a manufacturing process, and equipment that just needs a simple adjustment.
