What is sensor Module? What are different types of 
sensor?
◦A sensor module is basically an electronic circuit board that has been pre-
programmed with the appropriate software to perform a specific function. 
In order for it to work properly, it needs to be connected with the 
appropriate sensors.
◦The sensor module is designed to be used in a variety of applications. It is 
a device that is used to measure and record physical quantities such as 
temperature, pressure, light intensity, sound intensity and humidity.

There exist two types of sensors which detect 
motion with the help of Infrared, one is Active 
Infrared sensor (AIR sensor) and another one 
is Passive Infrared sensor (PIR sensor).
Infrared sensors (IR Sensors) are the sensors 
that work on Infrared sensing technology to 
detect the motion of objects. 
PIR sensors utilize the detection of infrared that 
is radiated from all objects that emit heat. This 
type of emission is not visible to the human eye, 
but sensors that operate using infrared 
wavelengths can detect such activity.
