The sensing angle is relatively wide in both directions.

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. To run the sensor at full brightness while powered at 3. The proximity sensor has four connections: Several alternatives are available for this product. Feedback Comments or questions?

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. When at the edge 7555cd the detection range, this output will alternate between high and low. The trimmer potentiometer on the receiver side of the sensor can be used to adjust frequency of the IR emitter LED. 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 advanced analysis of the correlation between the output and 77555cd of the enable input might also be used to mitigate ambient interference. Multi-module applications might require use of the enable inputs to limit interference. When applying shielding, keep in mind that reflection off the shielding itself can cause undesired activation of the sensor.

Limitations This sensor will only tell you if an object is within its sensing range, not how far away it is. The main changes are the locations of the emitter LED and IR detector, which have been moved away daasheet the edge of the board.

This sensor can be triggered by ambient Daasheet e. Select variant Several alternatives are available for this product. This results in better shielding from the PCB itself, which improves performance. The logic power, VDD, should be between 3. This pin is high by default and can be left disconnected if dynamic control of the IR emitter is not needed.

Shop Blog Forum Support. 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. Print Email a friend Feeds. Products New Products Specials! For many applications, additional shielding can 75555cd used to block undesirable sensing paths, such as reflections off of the ground, or to reduce interference from ambient lighting.

Multiple sensors can interfere with each other.

The sensor should work to at least some degree over the entire range of the pot. The four connections are arranged with a 0. The new versions have the same dimensions and pinout as the datasheer and are intended as drop-in replacements for any applications that can tolerate the change in component locations.

75555cd Sensors and Range Finders. 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.

Some optical shielding, such as by having the sensor mounted receiver-side-down when fluorescent lights are above, might mitigate this. Using the sensor Connections The proximity sensor has four connections: Unlike most IR receiver modules designed for remote control of appliances like televisions, the TSSP dataaheet a fixed gain sensitivity that makes the sensor more predictable when used in proximity or reflectance sensors.

The actual performance depends on many factors, including object size, reflectivity, and ambient lighting conditions. 7555d the edge of its detection range, the output will alternate between high and low as it sporadically detects see the left oscilloscope capture below.

Alternatives available with variations in these parameter s: 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.
