Irradiance/Illuminance Meter using TLR235R sensor with AVR Atmega

The TSL235 is a light-to-frequency converter. This library reads TSL235 output frequency and convert it to irradiance, and then to illuminance. Irradiance is the power of electromagnetic radiation per unit area (radiative flux) incident on a surface. It’s expressed in watt per square metre, the symbol is Ee. In photometry, illuminance is the total luminous […]
