hi everyone.
we asked to design a distance sensor with TSOP 1138. i've attached the datasheet here. the problem is that we have to sent square waves and then steady wave and so on. to create square waves i think we'll use square wave generator, but how to design this to make the square waves follow by steady wave?
can you help me to design this project?
here is a little description of project.
You may use resistors, capacitors, inductors, diodes, LEDs, IR-LEDs and op-amps. You can use maximum 3 DC supplies.
Your circuit is required to measure the distances of objects in the range 0-60 cm. For display purposes, you may utilize LEDs. At least four TSOP1138 IR sensors are required. In the range 20-60 cm receivers must be active and number should decrease as the object comes closer to the receiver in the range 0-20 cm. For
objects further than 60 cm, which is the maximum detectable range of the system, all LEDs should be off. The object, whose range will should be of size 10cmx5cm (width x
height), whereas depth is not important.
