A digital thermometer based on the D18S20 and WeMos D1 Mini1(ESP8266). I needed a thermometer to monitor the temperature in my sous vide. I created this to simultaneously meassure multiple temperatures in the water.
The prototype was asembled from this followingw way. The prototype was build with a J204A 20X4 LCD display. This have the same pinout as the illustration.
The source in SousVideLogger.ino is downloaded to the D1 Mini using the arduino IDE. The device can be powered via the mini USB on the D1.
