Adafruit module with Si7021 temperature / humidity sensor

Description

Adafruit module with Si7021 temperature and humidity sensor. Sensor Sillicon Labs can measure temperature in the range of -10 ~ + 125 ° C, and humidity in the range of 0-100 & RH. The sensor communicates via the I2C interface. The module has a 3.3 V stabilizer and a logic level converter. This allows for safe operation with both 3.3 V and 5 V voltage. A PTFE filter was applied to the system to protect the sensor from contamination.
