Abstract
A gas detection device and a gas detection process are capable of detecting a target gas. The sensor unit measures the target gas concentration and generates a target gas signal (con), which includes a temporal sequence of target gas signal values. If a target gas signal value is between a lower target gas threshold (con) and a higher target gas threshold, a target gas warning is issued. If the target gas signal value is greater than the greater target gas threshold, a target gas warning is issued. In addition, an aggregation signal (STEV, TWA) is generated, which is an averaging or accumulation of several target gas signal values. If an aggregated value is between a smaller and a larger aggregation threshold (STEV, TWA, STEV, TWA), an aggregation warning is issued. If the aggregated value is greater than the larger aggregation threshold (STEV, TWA), an aggregation alarm is issued.
