Can you tell us more about it?
The Hi-Link site has some detail but brings up a few more questions:
- do you have a datasheet detailing the serial comms?
- where do you have this deployed as the range looks somewhat limiting:
“Antenna half power angle horizontal ±57°, vertical ±24°” - how accurate is the “static body detection coverage radius 2m” ? this would be a deal-breaker for me
- does it output any additional information? (distance/direction/etc)
- what configuration parameters does it accept?
- what is the minimum hold/delay/latency for Occupied-to-Unoccupied?
We have learned from our SeeedStudio experience that the details can make or break a sensors use-case flexibility.
