I was wondering if we can use the following optical mouse sensors on our line following robots or for other optical sensing applications.

ADNS-2030, ADNS-2051, DNS-2610, ADNS-2620

they are all avaiable at RS Philippines.

actually you can use the sensors of the wheel in trackball powered mouse

i'm familiar with the phototransistor and LED combo but that setup does not have automatic calibration and you need to calibrate it depending on the surface and contrast of your line and your floor. The AVAGO chip used on optical mouse has a built in automatic calibration which allows it to function properly regardless of the surface reflectivity.

interesting, reading from their datasheets it seemed possible, parang may builtin image sensor na siya.

anyway has anyone tried the image sensor of cypress for theses types of application.

ayos pala yang Optical Mouse Sensor mapag-isipan nga kung ano pa ang pwedeng application. madali lang naman ma-interface sa microcontroller yan.

I have used the infrared LED/sensor pair from optomechanical mouse. Im not sure kung ano device name nito but its a great sensor, or should i say the best sensor, for line following mobots.

I also built a tachometer using that infrared LED/sensor.

Ok rin at available na ito. But i think mahirap siguro how to use this since it requires the DSP chip if im not mistaken

ahihi complete assembly na pala yan. The sensor plus the chip and others

gumamit din kami nito nung college for our project..
galing ung LED/sensor pairs sa mga lumang serial mouse..
yung sensor (black TO package, makinis yung front nya for daylight filter) is a phototransistor,
and yung LED (transparent package) is an infrared emitter.
