GP2D12 Optoelectronic Device

IR SENSOR enough for balancing.
you can directly access from internet for manual detail.

FEATURES
• Analog output
analog output make your job more easier, because you can directly connect to the PIC port. but remember that, the signal receive will have noise, then you need to filter it out. here i use capacitor 0.1uF. if you don't know the correct value please do an experiment.
• Effective Range: 10 to 80 cm
place your IR sensor in between the range for better performance.

• LED pulse cycle duration: 32 ms

• Typical response time: 39 ms

• Typical start up delay: 44 ms

• Average current consumption: 33 mA

• Detection area diameter @ 80 cm: 6 cm
