Ultraviolet rays, also known as UV for short are rays emitted by sun. Due to the depletion of the ozone layer, these rays tend to get to extreme levels that could lead to sunburns etc for those under it, that’s why daily and hourly forecast of the UV index is always available to help people keep track and stay safe. For monitoring purposes, why not own a personal UV meter?
Today, we will build a UV meter using the Arduino and the ultraviolet sensor (UVM30A) with a Nokia 5110 LCD display as the display for the meter. The Nokia 5110 is used to display the UV index which is an international standard unit for the intensity of ultraviolet rays from the sun being experienced in a particular place and at a particular time.
