Firstly, the range test as shown in the 8a,and the maximum range was found as around 6-9m, while the direction investigation was suggest that the circuit with the infrared blocker can sense the incoming infrared as the angle changed from -36o to +36o as shown in the fig 8b. From the result, it showed that the system can detect the direction of the infrared gate from 6-9m apart and also has direction range around 36o
