Infrared motion sensor Vega Smart-MS0101 is designed to detect penetration into the protected area. The sensor alternately operates in two modes: «Guard» and «Neutral». In the «Guard» mode, the device sends an alarm message to the LoRaWAN™ network when motion is detected, after which it switches to the «Neutral» mode for a while. In the «Neutral» mode, the sensor does not send alarm messages when motion is detected. If the movement in the protected area has ceased, the device switches back to the «Guard» mode. Vega Smart-MS0101 can be used to protect premises, buildings and structures, as well as in Smart Home systems, built on LoRaWAN™ technology.
