Interesting to consider: Alarm Conditions
They typically include inputs from other building control systems like the fire alarm or the HVAC system. Input of the kind could trigger an emergency “all lights on” or “all lights flashing” command.
PROGRAM LOGIC:
There is a microcontroller that the system takes advantage of to process all input signals from the sensors. It then makes decisions that are based on the program logic. They output control actions.
A control system manages and regulates devices or systems using the Input-Process-Output (IPO) model, where sensors detect input, a microprocessor processes data, and actuators execute actions. Systems can be open-loop(no feedback) or closed-loop(using feedback to correct errors, e.g., negative feedback for stability). Control can be centralized(one processor) or distributed(multiple processors).
This centralized system is a open-loop sound-activated automatic light switch that detects both sound intensity and ambient lighting conditions. The VU meter senses sound, while the LDR monitors light levels, converting these analog inputs into digital signals processed by a processor. When a person approaches (and makes a sound), the system turns the light ON for 1 minute if it is dark(sensed by LDR and determined by processor). This system is suitable for settings like hotels, corridors, garages, and basements.
Detects whether there is any movement in the corridor. If there is, it triggers the system.
It toggles the system by a sound pulse, detects a present sound pressure level. Sound sensor is defined as a module that detects sound waves through its intensity and converting it to electrical signals.
Generally, Delixi may use ADCs in order to process inputs from the sensors and DACs to control the outputs.
ADC – Convert analog output (LDRs) into some digital value; system assesses ambient light levels or, if in the case of the motion sensor, it converts the signal to determine whether motion is being detected.
DAC – dimming control by converting didgtal signals from the cs into analog signals. Could be mentioned that if the system has RGB, DACs could potentially control the intensity of each color channel on ‘digital input values’.
