Documentation and test for an Arduino/ADS1115 version of the InstESRE pyranometer kit
This repository contains documentation and a test program for a modified version of the pyranometer kit offered by Dr. David Brooks of the Institute for Earth Science Research and Education (InstESRE). An Arduino and ADS1115 analog-to-digital-converter are used to measure the photodiode output and translate that to an irradiance value. There is also support for a TMP36 temperature sensor co-located with the photodiode, allowing the software to compensate for the effect of temperature on the photodiode output.
The IV Swinger 2 IV curve tracer (csatt/IV_Swinger) supports this design as an optional sensor, and that was the motivation for its design. However, since other users of the InstESRE pyranometer may find it useful, this repository describes the design independently from the IV Swinger 2 project. The included Arduino sketch can be used to test (and calibrate) the hardware. It can also be used as a starting point for other projects (data loggers, etc.)
