Application of Sensors

1.Automotive

Sensors play an important role in both the manufacturing and operation of vehicles. Due to advancements in technology, modern cars have an even more complex set up of sensors. In the manufacturing process of cars, there are robotic arms containing sensors used to paint the body of cars. The thickness of the paint is also measured using sensors.
The Electronic control unit (ECU) houses all the hardware and software of the car. Data received from various sensors are processed here. Some common sensors found in cars are listed below.

Tesla uses ultrasonic sensors to detect cars close by which is needed for semi-autonomous self driving. It also increases safety as it can help prevent collisions.

2. Manufacturing

Sensors play a very important role in the operation of many manufacturing plants as well as the improvement of the efficiency of manufacturing processes. For instance, a temperature and vibration sensor can help detect if a machine is running irregularly. This provides predictive maintenance. Another application is in quality control. Various manufacturing parameters such as thickness, humidity and even protein can be monitored.

3. Aviation

During a flight, feedback on flight conditions and aircraft equipment are required to ensure the safe operation of the airplane. For example, flow sensors monitor the amount of lubricating oil, liquid coolant and other fluid moving in the system. Liquid level sensors check fuel, oil and coolant levels. Pressure sensors monitor pressure in hydraulic systems. This is very important as these systems are essential in landing and braking the plane.

4. Medical and Healthcare

Data collected from sensors in medical equipment and surgical devices are used by medical practitioners in diagnosis, treatment and control functions. Apart from equipment, sensors can also monitor the internal workings of patients during procedures. Some examples include glucose monitoring, robotics driven operations and automatic detection of visitors spreading disease to hospital patients.

Smart watches provide a very easy way to keep track of one's health. Motion sensors are able to detect the number of steps and physical movement a person does in a day.  An optical heart rate sensor helps monitor blood flow by detecting the pulse in one's wrist. This data is used to calculate heart beats per minute. Some watches are able to detect irregular heart patterns and alert relevant medical authorities based on this data.
