4 channel temperature logger with Arduino, SD card, LM335 and ADS1115
I improved my previous thermometer - datalogger circuit. Previously, I made a similar circuit, but just for to demonstrate how easy to collect the data of a sensor and write the data on a SD card.
Now, there was a real demand for a 4 channel thermometer. My Peltier experiments need several thermometers, because I want to get the readings from different areas/zones of the experimental setup. So, I found some sensors laying around and I decided to build this equipment. It turned out great at the end.
Read the code, too, it contains a lot of info. The wiring is in the video and code too.
