3.4.5. Lighting PIR Sensor

Lighting PIR Sensor

Automatic lighting control using a sensor Passive Infrared PIR sensor, passive infrared sensor connected to a digital input DI1.

In this example details the firing automatic lighting in the home automation network using presence sensors.

Amplifier

  • 1 analog output AO1 (PowerLed) of the Unit1 connected to two LED lamps (<12V each).

Control

  • 1 digital input DI1 of the Unit1 connected to a PIR sensor with digital output.

Program

The program is directly dependent on the type of occupancy sensor used for this example has been a sensor with digital output. Where is detected, the sensor provides a logic 1 when it detects the presence and delivers a 0. The output logic levels are reversed PIR sensor to digital inputs of the home automation controller (these are activated by level 0), therefore the program will have to reverse the process.

When it detects the presence of DI1 signal goes from 0 to 1, Off event occurs, which sent the process of lighting the LED lighting with the process value 100% in September. At the end of the detection of input DI1 switches to state 0, On event occurs, we send the process off to shut off the LED lamps.

Control of presence with multiple lighting levels

Playing with the processes and actions you can perform all sorts of combinations. Suppose we want to optimize energy efficiency in traffic areas (corridors, entrance area, reception ..). Establish a small permanent illumination when it detects the movement of people turn on the light to 100%, the program would be:
