So, in this Arduino interfacing tutorial series let’s look at such a sensor module built around the TSL25911 light sensor. TSL25911 Ambient Light Sensor Module. This is a high-sensitivity digital ...

To use the Keyboard you simply place your finger over the light sensor. A light will flash three times. Now on each following flash you will cover the light sensor or leave it. There is a list of ...

This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. Commonly available ...

Basically, humans need sufficient lighting with varying intensities for different needs, so it's important to know the intensity of light. A luxmeter is used to measure light intensity, but it's hard ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

The light is reflected off of the target such as a red piece of paper and returns to the sensor. The receivers are tuned to look for a specific wavelength of light working out its Red, Green and Blue ...

The light intensity controller automatically varies the brightness of an LED light depending on the natural light available in the room. In addition to this is room temperature and humidity monitoring ...

Tip: learn how to power light bulbs using Arduino with a relay module. What You’ll Need. If you’re ready to get started, you’ll need these items to get this project off the ground. Hardware. HW-479 ...

A light meter is a very useful device that finds applications in hospitals, schools, factories, parking lots, passageways, and many more to measure and maintain adequate lighting levels. It is also ...
