In this project, we selected a proper IR receiving component and designed the circuit in a way to act as stable as possible. Also, you can adjust the sensitivity of the sensor to detect the obstacles located near or far from the sensor.
You can examine the schematic diagram in the figure The famous chip is used to produce a 38KHz square wave. Frequency of the wave can be adjusted by turning the R5 potentiometer.
It typically reacts to the 38KHz IR pulse and activates its output.
PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor.
The figure-2 shows the designed PCB for the circuit. If you could not find something to put between the sensors, just cover the 5mm IR diode with a black heat-shrink and allow the light to exit just from the front.
Vishay just edges this round based on the Data sheet, particularly as the VSB data sheet that I found seemed to have the identity of the manufacturer removed. If you do know the manufacturer please post a comment below.
Round 3 — The Performance We are currently designing a range of IR PCB modules, to be launched in the coming months and for one of them we decided to evaluate the VSB with a view to replacing the existing Vishay model in the design, in the hope of driving costs lower. We tried a number of tests with standard IR protocols and also with longer Air Conditioner protocols which so often cause problems for IR receivers.
The good news is that both units handled every signal we launched at them very well. The Vishay always reported idle as expected under the same conditions. However, we still thought it could be some noise from the power supply and decided to wait for the sun to go down to test again.
We have had many reports from around the world, of successful IR decoding using this method with free code which is available for download. To get a list of our suggested Infrared receivers from Vishay check out the details of our handy IR component kits which can be seen here. Data sheets.
