UV meter for Old photography process, like Van Dyke, Cyanotype, etc.
Welcome to the UV meter & posemeter wiki!
I describe a simple tool and code to realize a UV meter. Based on
- Arduino ProMini 328P 3.3v 8MHz (no USB connector in ProMini in order to, for example, reduce power consumption)
- RTC DS3231
- screen SSD1306_128 * 64
- UV cell MT8511
- and : wires, holder battery, battery, case, etc...
The UV cell is fixed at the end of a flexible cable to be able to more easily make a measurement behind negative or positive film/rodoide.
In the LCD screen I'displaying:
- Date, MM, SS ( displayed in yellow)
- UV intensity (mW / cm ^ 2) instantaneous (displayed in blue)
- UV intensity (mW / cm ^ 2) total from beggining (displayed in blue)
- UV intensity (mW / cm ^ 2) per minutes (displayed in blue)
what serves me as a basis for comparing UV exposures by lamp or outdoor or sun, or cloud ...
