detection range affect the accuracy of the sensor. To overcome this problem, a bright
LED can be placed near to the sensor to give extra light at surrounding of the sensor.
In other hand, the error might due to the sensor fail to detect actual position of
occupant. For instance, sensor calculates the height of visitor‟s shoulder or their
hands from above.
At the earlier stage, when the program tested by using push button on SK40C,
the system function correctly but when all parts combine together, the output is not
as desired. Study had been conduct observed that the time interval to be broken
between both sensors is too small. This also due to the distance between the two
sensors and after a few calibrating and re-tested done, the system can function as
proposed. This sensor also needs to be calibrating to obtain the actual output.
