This schematic is also available as a downloadable pdf k pdf. The sensing angle is relatively wide in both directions.
Multi-module applications might require use of the enable inputs to limit interference. This sensor can be triggered by ambient IR e. Shop Blog Forum Support. The trimmer potentiometer on the receiver side of the sensor can be used to adjust frequency of the IR emitter LED. The main changes are the locations of the emitter LED and IR detector, which have been moved away from the edge of the board.

If you have the appropriate equipment, you can tune it by setting the actual frequency, but a simpler approach is to just observe the performance as you turn the pot. The logic power, VDD, should be between 3. Several alternatives are available for this product.
Select variant Several alternatives are available for this product. The new versions have the same dimensions and pinout as the dataseet and are intended as drop-in replacements for any applications that can tolerate the change in component locations. Proximity Sensors and Range Finders. You can use several of the proximity sensors with these discrete IR receivers to make sophisticated sensing solutions in which you enable one emitter at a time and monitor the reflections with the other sensors.
Multiple sensors can interfere with each other.
This pin is high by default and can be left disconnected if dynamic control of the IR emitter is not needed. Products New Products Specials! The sensor should work to at least some degree over the entire range of the pot.

To run the sensor at full brightness while powered at 3. Alternatives available with variations in these parameter s: Tuning the emitter frequency The trimmer potentiometer on the receiver side of the sensor can be used to adjust frequency of the IR emitter LED. Some optical shielding, such as by having the sensor mounted receiver-side-down when fluorescent lights are above, might mitigate this.
The proximity sensor has four connections: When at the edge of the detection range, this output will alternate between high and low. Some advanced analysis of the correlation between the output 755c5d toggling of the enable input might also be used to mitigate ambient interference. Schematic diagram This schematic is also available as a downloadable pdf k pdf.
The actual performance depends on many factors, including object size, reflectivity, and ambient lighting conditions. Print Email a friend Feeds.

When applying shielding, keep in mind that reflection off datasheef shielding itself can cause undesired activation of the sensor. This results in better shielding datasheer the PCB itself, which improves performance. The four connections are arranged with a 0. The sensor is merely looking at whether or not it is getting any signal back, so object size and reflectivity to IR will affect sensing range.
Feedback Comments or questions? Limitations This sensor will only tell you if an object is within its sensing range, not how far away it is. Using the sensor Connections The proximity sensor has four connections: A red LED on the emitter side of the board is tied to this output and turns on when the pin goes low, providing a visual indication of when the sensor is detecting something. An enable input allows control of whether or not the IR LED is on, and a digital output indicates whether or not an object is detected.
Unlike most IR receiver modules designed for remote control of appliances like televisions, the TSSP has a fixed gain sensitivity that makes the sensor more predictable when used in proximity or reflectance sensors. At the edge of its detection range, the output will alternate between high and low as it sporadically detects see the left oscilloscope capture below.
For many applications, additional shielding can be used to block undesirable sensing paths, such as reflections off of the ground, or to reduce interference from ambient lighting.
