VOC, Humidity and Temperature Sensor Board

The board includes two sensors from Sensiron:

• SGP41-D-R4 VOC and NOx sensor,
• SHT41 temperature and humidity sensor. The sensor data is accessible via UART interface. The voltage level is 5V, but the input is 3.3V compatible. A TXU0202 level shifter is used. The sensor board is intended to be used with other Sensiron sensors (like SPS30 and SFA30). The 5V interface was chosen so that a central controller can use the same interface type to connect to any of the sensors.
