What is a sensor and its types?
  
A sensor is a device that detects or measures a physical 
property and records, indicates, or otherwise responds to it. 
Various types of sensors exist with different prices 
depending on their type and intended use; for example, 
humidity or temperature sensors can be bought cheaply, 
while motion and smoke detectors tend to be significantly 
pricier due to their more complex applications. Regardless 
of the sensor's price, they can play an important role in all 
areas of life, ranging from home security systems to 
industrial imaging technology.
