3.2. LED Light Bar

The LED light bar is used primarily as warning indicators. To accommodate various

requirement, two type of LED light are available for control, namely Red and Blue. In general,

red lights represent warning/alert and blue lights represent normal condition. The LED lights are

control with different digital output of the embedded board, making it also possible to turn both

LED on simultaneously. In general application, either red or blue light are used at a single point

of time.

3.3. Buzzer

The buzzer is used together with the LED light to constitute the effect of alarm. Only on/off

control can be set.

3.4. Counter

The eight digits counter is used to record the amount of people that go through the gate.

The detection is normally done through IR sensor. The counter can also be reset

programmatically if there is special request. In general application, software counter is used

because software counter offers the flexibility of counting visitor within a period of time.

3.5. PIR Sensor and IR Sensor

The PIR sensor is meant to detect human motion that it faced within a distance of

approximately 2M. The IR sensor is meant to detect people walking through the equipment.

Both sensors can be used to trigger activity such as tag detection, alarm or counting.

The IR sensor installed is retro-reflective type. A reflector is located at the other side of the

panel (image #3 as shown below). If an object or person comes in between of the IR sensor

and the reflector, the IR sensor signal is triggered. This can been determined by looking at the

orange LED light of the IR sensor. When there is nothing detected, the orange LED is off

(image #2).
