As seen in Figure 1: "PIR sensor", these sensors contain two parts that are sensitive to IR. Since it is motion that is important, the signal delivered by the sensor reflects different amounts of IR detected by each part. If both parts "see" the same a...

This paper presents an innovative multi-resident activity detection sensor network that uses the Bluetooth Low Energy (BLE) signal emitted by tags worn by residents and passive infrared (PIR) motion sensors deployed in the house to locate residents and monitor their activities. This measurement system...
