The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for build a weather stations or humidor control system.

A look at the SI7021 Temperature Sensor with Arduino and

/16/2016Si7021 Humidity and Temperature Sensor Library This library was made for the Si7021 Humidity and Temperature sensor and only tested on the teensy 3. 1 but it should work for Arduino also. The Si7021 is an I2C device that runs on 3. 3v, it has four pins broken out, two for power and two for I2C so connecting the sensor is pretty straight forward.

I2C Temperature Sensor Communication Issue - Arduino Stack

Depending on the conversion command, the Si7021 may hold the master during the conversion (clock stretch). At above 100 kHz SCL, the Si7021 may also hold the master briefly for user register and device ID transactions. At the highest I2C speed of 400 kHz the stretching will be s. 3. Pulses up to and including 50ns will be suppressed. Table 2.
