The TVOC sensor is a fixed continuous monitor for the detection and measurement of total volatile organic compounds, which can be dangerous from both a poisoning and explosive perspective.
Requires analog port selection during U30 system configuration and use of a S-FS-CVIA when using the H22-001 logger.
