Output OUT (pin 3) of IC2 can drive two of these IR-drivers without any difficulty. The receivers are slightly different than those of the modulated light barrier and the circuit is the same for both types of installation. We again use the TSOP1736, which is sensitive to IR-light that is modulated

This circuit has a range of several meters, even if the sun shines directly on the receiver! We use the exact same IR-transmitter(s) as for the modulated light barrier. For the installation with two separate IR-transmitters it is sufficient to duplicate R6, T1, D1, C3 and R7 from the circuit of the modulated light barrier.

AN01 – Application Note Light Barrier Concepts Introduction The illustration below shows a typical light barrier application. The transmitter emits a modulated light signal to the detector. If there is no obstacle between the transmitter and the detector, the modulated transmitter light can be received by the detector. If an obstacle blocks the

help with this, the light barrier described here can be used to guard an entrance. You can use it to signal of someone is walking through the corridor, or to check if the car has been parked far enough in the garage to be able to close the door. The circuit consists of a transmitter, which sends modulated infrared light and a receiver, which

The first transmitter emits light pulses with an identifier for synchronising the pair and the received signals from the receiver element are compared with defined desired values to check for error-free operation of the pair. Each residual transmitter element per cycle emits only one pulse position modulated light pulse.

Contactless monitoring of a protected area is achieved by a transmitter (1) consisting of a series of i.r. diodes (2,3,4) periodically and cyclically switched on in sequence to transmit modulated light. The receiver has a corresp. number of photodiodes operated periodically and cyclically and assigned to their own sender diodes. A multichannel evaluating unit in the receiver generates a signal ...

The circuit for this has many similarities with the modulated light barrier appearing else-where in this Summer Circuits issue. There are two ways to position the light barriers, namely a completely duplicated installation in opposing directions (this to prevent mutual interference) and a version with one IR transmitter and two receivers.
