This motion sensor from the company Browan with LoRaWAN reacts to movements of people and animals. When a movement is detected, a data packet is transmitted immediately. In addition to the trigger, this packet also contains a counter for the number of events recorded so far. After five minutes of no movement being recorded, a packet is transmitted again to signal that there is no more movement in front of the sensor. Subsequently, a data packet is transmitted every hour to indicate that no further triggering has taken place and how long no movement has been registered. All data packets contain information about the battery status.

PIR motion detector or ToF sensor
PIR motion detector
How a PIR motion detector works:
The PIR motion detectors (passive infrared sensors) are named after pyroelectricity, whereby a change in temperature leads to a measurable change in electrical voltage. Every living organism emits infrared radiation. A change in the heat source registers that something is moving and, depending on the design, in which direction it is moving. PIR motion detectors are therefore often used as light motion detectors, whereby the light is activated when a PIR motion detector registers movement.
Applications of a PIR motion detector:
PIR motion detectors are key instruments in smart facility management. They regulate the motion detector light in offices and public spaces, reduce energy waste and increase comfort. At the same time, they detect unauthorized access, contribute to security and enable efficient lighting control as part of smart facility management.
ToF sensors
How a ToF sensor works:
The ToF sensors are named after the term Time-of-Flight, which also describes exactly what happens with these IoT sensors. They measure the time it takes for the emitted light to be reflected and to arrive again. Depending on the model, several fields are used to register not only whether something is in the entire area, but also the differences within this area. This can be very helpful in applications such as offices or business premises where user behavior is also relevant. Together with learned patterns through AI, ToF sensors can be the basis for many intelligent applications.
Applications of a ToF sensor:
ToF sensors are valuable tools in smart facility management. They enable the precise recording of room utilization in offices and event rooms as well as people counting with directions of movement. As effective people counters, ToF sensors record the presence of people in real time and enable demand-oriented use of the premises as part of smart facility management.
