MyLCD20x4 Clock with Value-Added Information

Use a Particle Photon, a SHT31-D sensor, and a cheap LCD20x4 to start your own clock project.

Recycling good
Since 07/2017, my desk clock powered by a Particle Photon runs smoothly with a BME280 and I thought it was time to change the structure slightly and to bring even a more precise temperature and humidity sensor to use.

Here I decided for the SHT31-D with a chip from Sensirion, which is distributed as a breakout board by Adafruit. The data sheet speaks of deviations in the decimal range and so I describe the uncomplicated conversion while maintaining the transmission protocol I2C.”
