Ir Sensor work on 3.3v or not ??
« on: December 22, 2011, 01:07:29 AM »
hi, i m little bit confuse there, i am going to make, line follower robot, using IR sensor also i m using mobile phone battery, 3.7 (using regulator 3.3 v ) volt and  my question is :

did ir sensor work on 3.3 volt perfectly or not,.,
using 6 sensor
mobile battery current : 850mA

did any one did it before?
waiting for reply,.,....  :-[

Hi,

[...] i am going to make, line follower robot,
Which line follower?
Please post a link when you mention something like that - we're good, but we're not psychics ;D


using IR sensor also i m using mobile phone battery, 3.7 (using regulator 3.3 v ) volt and  my question is :
Don't use a regulator.
Regulators need voltage to operate. THE LDO variety up to ~1V and the regular types up to 3.5V - neither of them would be very helpful.

The cell phone battery will only be 3.7V when freshly charged and it discharges down to ~3.0..3.3V.

Unless you use equipment that cannot handle 3.7V, you have absolutely no reason to use a regulator and even in the unlikely case, a zener would be the only really useable solution.


did ir sensor work on 3.3 volt perfectly or not,.,
You have to tell us which sensor you are talking about.


using 6 sensor
mobile battery current : 850mA
The motor(s) will probably have the major current draw.

Now there's a surprise  ;)
