R311B is a Wireless Light Sensor based on the LoRaWAN open protocol (Class A). When the illuminance exceeds the set threshold, a report will be sent immediately. Main

  1. LoRaWAN Class A compatible
  2.  Frequency Hopping Spread Spectrum (FHSS)
  3.  Improved interference immunity
  4.  Improved power management for longer battery life
  5.  Battery Life*2:
    1. Please refer to web: http://www.netvox.com.tw/electric/electric_calc.html
    2. At this website, users can find battery life time for varier models at different configurations
  6.  Over-the-air updates (future)
  7.  Third-Party online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email (optional)
  8.  Available third-party platform: Actility/ThingPark, TTN, MyDevices/Cayenne

*1. Actual range may vary depending on environment.
*2. Battery life is determined by sensor reporting frequency and other variables
