Sensors required for operation are: TeraHz depends on three separate sensor boards:
- AS7265x - AS7265x spectral chipset
- VEML6075 - VEML6075 UV sensor
- APDS-9301 - APDS-9301 lux-meter
They provide the spectrometry data, UV data and illuminance data, respectively.
They all support I2C, AS7265x supports UART in addition.
