The 8-pin terminal blocks arrived early this week. We've now mounted our sensor board onto the router board and connected the 4 sensor ports to the terminal block.

Flukso sensor node internals

Since our first prototype implementation based on an Arduino and Fonera 2200 hybrid late last year, we've been busy designing an integrated sensor board for Flukso, our community metering application. The board has an ATmega168v microcontroller (uC) at its core and contains sensor debouncing and signal conditioning circuitry. We can connect one analog and up to three digital pulse sensors to the PCB. Power (3.3V) is drawn from the 4-pin UART header of the main router board.

Last Saturday I attended the second edition of Homecamp at Bash Creations in London. You can find the Flukso slides I presented on community metering here. All in all, it was an interesting day, packed with presentations and loads of conversations on home monitoring and automation, drained in a big sauce of sustainability. Despite being an unconference, you still need a group of people pulling it all together. So a big thank you to Chris Dalby of Yellowpark, James Governor of Redmonk and anyone else who helped in organising this second Homecamp!
