I am doing a project in which i have to count the no.of. vehicles passing a signal in a particular lane. Which type of sensors can be used to count the vehicles..? If ir sensors can be used,is it possible to design ir transmitters and receivers in the range of 40 to 50 meters or more..? or Are they readily available in the market..? ....etc

Introduction of IR music transmitter and receiver



Abstract

The infrared radiations are transmitted and received by ir leds and photo transistor respectively
The project emphases the way by which music is generated and driven by ir rays
The main idea behind this project is to generate musical notes by infrared radiations
The circuit uses popular melody generator IC UM66.
It can be used in wireless music systems.
