Granular Radio EnErgy-sensing Node (GREEN)

This device implements a mesh network. Conceivable applications include distributed environmental sensing, household monitoring and any other space where many small sensor nodes are required. The current use case being explored is circuit-breaker panel monitoring using GMR magnetic sensors to measure current flow to household loads. The current range test yields 175m with a 38.4K serial link and Atmel’s Lightweight Mesh software stack.

The radio board features:

  • 7.5 x 7.5mm
  • ZigBee – compatible 2.4Ghz RF tranceiver (integrated)
  • Atmel AtMega2564RFR2 8-bit MCU core
  • 5xADC channels, SPI, I2C, UART, JTAG interface
