A standalone LoRa siren
The ACS-Switch-Buzz combines the various features of the ACS-Switch (motion, tilt, and rotation detection) with an added audible alarm. The ACS-Switch-Buzz can automatically trigger its siren based on its own sensor activations, but it can also be remotely controlled by external events (such as proximity of people, movement of hazardous equipment, activation of specific processes, etc.).
A new version
This new version provides an additional solution for industrial process safety by enabling real-time alerts to workers about risks or abnormal events.
Thanks to its smart sensor (tilt, motion, magnetic environment) combined with its buzzer, the ACS-Switch-BUZZ can be used both as a safety warning device and as a process alarm. When paired with other sensors, it alerts you to processes that are not followed or poorly executed.
