For more information on DALI, please read " What is DALI ?" article.įrom a constructional standpoint, light level sensors can be either stand-alone devices or they can be integrated with a microwave or passive infrared occupancy sensor into a single unit. The application controller will then generate appropriate DALI commands to instruct the affected lighting groups to get brighter or dimmer. A DALI enabled sensor will output a digital signal onto the DALI bus that indicates to the application controller the light level that has been detected and the identity (or address) of the sensor involved. The most common digital signal protocol in use now (2021) is DALI. This is commonly known as an analogue control signal – the output voltage is (inversely) analogous to the light level that has been detected. The output voltage is inversely proportional to the light level detected, meaning that when the sensor detects a high lux level the voltage output will be low and when it detects a low light level the output voltage will be high. Most commonly the voltage output will be variable between 1-10V. These will have a variable output which can be either of two types. Light sensors for on/off and dimming control.Their function is to turn lights on or off. From a practical, or application, standpoint they fall into two types: Light sensors, also known as lux sensors, are widely used in a variety of lighting control applications.
