circuit proxsimity sensor tsop

Hai

I am looking for a proximity detector circuit for a moving Toy project. Preferably using Infra red signal detection.
Plaese .. Links or circuits.
or any commercial units available in India.

Hi,
U can use IR reflection metod using TSOP 1738 sensors(TV remote sensor). i have practically realised this during my college days.
u can modulate a low freq signal on a 38khz carrier using pic.( use interrupt and pwm module for this) and limit sensitivity of the sensor.

Hai
the IR receiver responds to make and breake beam only.That could be handled.How to reduce or adjust the sensitivity of the receiver to detect the reflection ? Please Suggest

Hello!

See the link below. You'll find my plans for a simple IR Obstacle Detector with pictures and Eagle files.

you must look at this site.. www.alexan.com.ph in the philippines.. ultrasonic sensor emits sound.. it has a transmitter and receiver.. you may choose a better sensor so you creates a circuits that appropriate in your project.. proximity is also the sensor you may use also.
 

I have same prob. I want to make a sensor to measure distance from 8cm to 40cm with 4cm presicion. If you have pls share the circuit diag.
