How Does a Digital Luxmeter Work?

Luxmeter uses photodiode, a light-sensitive sensor for measuring the intensity of light. The current passing through the sensor is dependent upon the intensity of light, as the intensity of light varies, the reading on the luxmeter also varies. The output of the sensor is processed and sensed by a microcontroller and according to the voltages, the microcontroller generates light intensity reading.

Modern luxmeters have several more functions such as storing readings, applying filters, pausing a value and connecting with computers via USB.


Applications of Digital Luxmeter:

Luxmeters have several applications, especially in engineering discipline. Whether an engineer is ensuring the directions of Solar Panels is according to the light orientation or the light intensity in an office is being monitored or a student-level home automation project is being developed, a luxmeter can be helpful.

  • When a new Solar Power System is installed, it is essential to keep the direction of Solar Panels according to the orientation of Sunlight. Ensuring proper direction may result in maximum power generation. The luxmeters are helpful in monitoring the light intensity at various positions and accordingly Solar Panels are tilted at a certain angle.
  • Low light or high light intensity in offices and schools can result is fatigue, it is necessary to keep proper light in places that are illuminated through synthetic light. Luxmeters works well for measuring indoor light intensity.
  • When it comes to home automation, switching off lights, closing/opening curtains according to the light intensity are one of the most interesting features. For precise handling of light intensity, luxmeters are used for reading light intensity.
  • Street lights can be automated to turn on/off according to the availability of light. But a more interesting project can be to develop a more power-saving project that controls the intensity of street light according to the need. A street light that illuminates partially at low sunlight and the intensity of light increases as the sunlight starts vanishing.
  • Professional Photographers and videographers always consider light intensity before shooting. Digital luxmeters are useful for such people as these smart devices auto turn off if not attended for long, they are lightweight and easy to carry anywhere, and their low power consumption enables the batteries to last for long.
