When there is no obstruction in the path of IR rays, alarm will be silent. When somebody crosses the IR beam, alarm sounds.

Photo sensors are used in many projects involving sensing of light or shadow. Light Dependent Resistor (LDR), Photo Diode, Photo Transistor and Photo Darlington Pair are some of the . Photo transistor L14Fis used as the IR Receiver. So light exactly focus on the base semiconductor and the photons in the light gives bias and it conducts. A brief tutorial about how to use phototransistors to detect light.

This is an Infrared based Broken beam alarm to protect doors and entry passages. It can protect the doors both day and night and is free from false triggering. Customers who bought this product also commonly purchased the following combination of items. Phototransistors Phototransistor (piece): Amazon.

This improved infrared detector is specifically intended for use with commercial IR remote control handsets. This Circuit can monitor the door steps or Staircase. The circuit is too sensitive and operates in day light.

It senses the intensity of light through its exposed base and passes current in the . It uses infrared photo transistor as fire sensor. Circuit and working Circuit diagram of the light-sensitive fire alarm is shown in Fig . It is built around L14Fphoto transistor (T1), BC5transistor (T2) and NE555 . White LED turns on when IR present. Find out information about phototransistor.
