A detection assembly operable to detect a refrigerant leak event includes a sensor network and a controller. The sensor network is operable to generate sensor outputs including triggering-sensor (TS) outputs and triggering-sensor context (TSC) outputs. The controller is operable to perform a sensor-reading context analysis on the sensor outputs. The sensor-reading context analysis includes accessing a set of the sensor outputs that occurred within a context time window, along with determining that a pattern of the set of sensor outputs represents the refrigerant leak event.

The present disclosure relates to detecting presence using a low-cost radar. A transmitted signal including repetitions of a transmitted signal is emitted from a transmitting antenna. A received signal including a combination of a plurality of reflections of the transmitted signal is received at receiving antennas. For each received signal, the received signal is processed to determine whether a threshold has been exceeded. When the received signal exceeds the threshold, presence due to a motion from a moving body is determined. When the received signal does not exceed the threshold, a periodicity of the received signal is measured to determine whether the periodicity of the received signal is within a vital range, and presence due to a vital sign is determined when the periodicity is within the vital range.
