R311CA LoRaWAN Wireless Dry Contact Sensor Node

The R311CA device has a built-in reed switch sensor, and can be connected to a certain number of reed switches through external expansion. It can be used for door and window switch status detection. It can realize wireless alarm and other functions through built-in wireless module, and is compatible with LoRaWAN Protocol. It can be easily networked with other related devices. The R311CA is durable and ensures optimum use and is a low power consumption device. Due to their small size, they can be installed anywhere, they are wireless, so they take up very little space.

Features:

  • Wireless Range Of 10 Km
  • LoRaWAN™ Class A Compatible
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved Interference Immunity
  • Improved Power Management For Longer Battery Life
  • Encrypt-RF™ Security (Diffie-Hellman Key Exchange + AES-128 CBC For Sensor Data Messages)
  • Battery Life*2:
    ⁻ 5 Years

     (Conditions: Ambient Temperature 25 °C, 20 Triggers/Day, Txpower = 20dBm, LoRa Spreading Factor SF = 10)

  • Over-The-Air Updates

  • Third-Party Online Wireless Sensor Monitoring And Notification System To Configure Sensors, View Data And Set Alerts Via SMS Text And Email (Optional)

  • Available Third-Party Platform: Actility/ThingPark, TTN, MyDevices/Cayenne
