Head IR sensor
IR sensor is located infront of the Head Module above the eyes. IR sensor is used for trigger the robot to start when
user wave their hand infront the face of robot.
Head Sound Sensor (Microphone)
Microphone is located inside of the Head Module and it is invisible from outside. Microphone can be used to detect
maximum sound volume, trigger robot to start by hand claps.
It has features of capturing maximum sound level detection, hand clap counter and current sound volume level.
Sound volume is sampled at sampling frequency of 3.9KHz. User can set threshold level for the hand clap detection.
Hand clap detection is done at interval of 800 miliseconds. This means that, when a clap has been detected, the
sensor will ignore any claps within the 800 miliseconds, sensor will only detect for second clap after 800 miliseconds.
This to prevent a single clap being detected as multiple claps.
