Flipper Temperature Sensor - HTU21D / SI7021

Original link

What is this?

A small app for the Flipper Zero that reads the I2C signal from a HTU21D or Si7021 sensor and displays the current temperature and humidity.

I'm using a Sparkfun HTU21D sensor, also tested with a clone and with the Si7021 variant.
