Occupancy in a room
If you need the exact headcount of persons entering a building or room, it’s better to go for another technology like turnstiles or cameras with face-matching technology as PCR2 is not able to count people walking in rooms side by side.
Many people think of LoRaWAN devices as battery-powered sensors with years of battery life. LoRaWAN data transmission is in fact very energy efficient.
Unfortunately, the integrated radar sensor needs too much energy to get a useful operating time with batteries.
Therefore, all PCR2-IN are externally powered. However, we do have solar powered devices for outdoor use.
