SFA30 Formaldehyde Sensor
The sfa30 sensor platform allows you to use your Sensirion SFA30 Formaldehyde
(datasheet) sensors with ESPHome.
The I²C Bus is required to be set up in your configuration for this sensor to work.
This sensor supports both UART and I²C communication. However, at the moment only I²C communication is implemented.
