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 ...

The ADS1115 has four analog inputs it is easy to connect the voltage divider and the current sensor to this module. The maximum sample rate for the ADS1115 is 860 times per second so the delay between ...

This custom-built micro-lab uses an Arduino Nano to automate ammonia detection in blood and urine. It features a laser photometer, magnetic stirrer, PID-controlled heating, and a high-precision ADC ...
