Features

Generic Node (Sensor Edition) Node is a LoRaWAN® node containing multiple on-board components and peripherals, and with the provided SDK you can easily build IoT applications.

The additional strong end to end encryption and firmware over the air update in a device make it a roaming, secure and low-cost sensor that lasts on a battery for many years.

When the device is in the field, it will be the same device from production all the way to installation, which will bring immense economies of scale advantages.

  • End-to-End Encryption
  • Firmware Over The Air Update
  • Ultra Low Power:~1.8 μA in sleep mode
  • Standard Replaceable 2xAA alkaline batteries
  • Open Development Tools: Hardware Setup(Sensor Edition Hardware Setup | Generic Node)and Software Setup (Sensor Edition Software Setup | Generic Node)
  • Pre-provisioned on The Things Industries | LoRaWAN Network Server (i.e. The Things Network)
  • Open design (source-available) (GitHub - TheThingsIndustries/generic-node-se: Generic Node Sensor Edition)
  • The STM32WL55CCU6 Dual-core M4/M0 + SoC integrates a low-power microcontroller and a sub-gigahertz long-range radio. 
  • The onboard sensors and peripherals can measure temperature and humidity, and the accelerometer can detect the movements and vibrations with high accuracy. 
  • A user button, an RGB LED and a buzzer for getting user input and providing visual and audible feedback.
