This is an IR beam breaking alarm ideal to use in entry or passages. It is based on the working of the popular IR sensor Module TSOP1738 which senses 38 kHz Infrared pulses from the IR LED of the ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an ...

First, I built the circuit on a piece of prototyping board (experimenting PCB). Here’s a photo of my prototype: Because the design is based on the IR sensor module TSOP1838 from Vishay, it inherently ...

The sensor module is RoHS-compliant, halogen-free, and Vishay Green. Samples and production quantities of the TSSP77038ETR are available now, with lead times of eight weeks.
