AVT2794 A

The automatic lighting controller is made on discrete components and logic circuits without the need for a microcontroller. Its operation consists in counting people entering and leaving the monitored room. At the moment when no one is inside, the light is off, otherwise - it's on.
The system works on the basis of an infrared barrier. The use of two transmitting / receiving units limits the possibility of false readings and ensures correct counting in the right direction.

The device is particularly recommended in rooms where many people scroll, in shops, offices, etc.

Selected parameters:

• two infrared tracks
• modulation of infrared beams
• output circuit - relay
• galvanic separation from 230 V mains
• built-in voltage stabilizer
• power supply - 10 Vac
• in the set, printed circuit boards and documentation
  
  A version with a set of components for self-assembly is available
