Human-building　interaction　is　an　emerging　field　of　study　that　investigates　the　interactions　and　reciprocal　impacts　of　humans　and　building　systems.　In　this　discipline,　sensing　technology　is　critical　for　data　collection.　The　application　of　sensing　technology　is　divided　into　six　categories　based　on　the　research　topics:　(1)　occupancy　status,　(2)　occupant　physiological　indicators,　(3)　building　components,　(4)　building　environment,　(5)　building　consumption,　and　(6)　fusion　of　multi-sensing　system.　By　evaluating　127　relevant　research　articles,　this　study　attempts　to　provide　a　systematic　review　of　the　implementation　of　sensing　technologies　in　each　HBI　research　topic.　Four　significant　sensing　technologies　were　investigated　for　the　occupancy　status　study:　camera-based　sensing,　infrared-based　sensing,　radial　frequency　signal-based　sensing,　and　ultrasonic　sensor.　Methodologies　for　biosensing　brain　activity,　muscle　and　skin　function,　and　cardiac　function　were　examined　as　occupant　physiological　indicator　measurements.　The　magnetic　reed　and　vibration　sensors　were　discussed　for　sensing　changes　in　building　components.　The　air　property　sensor,　sound　sensor,　and　illuminance　sensor　were　introduced　to　monitor　the　building　environment.　The　smart　meter　and　smart　plug　were　examined　for　sensing　building　consumption,　and　the　application　of　multi-sensor　fusion　was　also　included　in　this　article.　Furthermore,　this　systematic　study　discussed　three　aspects　of　contemporary　sensing　technology　deployment:　data　concealment,　sensor　cost　tradeoffs,　and　privacy　concerns.
