Wire things up
Follow the instructions in ConnectingRadioModule to connect radio module.
Connect the IN1 and IN2 of relay to digital pin 3,4 of Arduino board.
Connect VCC to +5V of the Arduino board. GND to GND.
I used a dual relay module. But the code can easily be adapted to handle more or less relays by modifying RELAY_1 (which digital input first relay is connected to) and NUMBER_OF_RELAYS defines at the top of the sketch code.
Hardware - Purchase guide
To build this sensor you'll need one arduino + radio specified in the base kit found here:
http://code.mios.com/trac/mios_arduino-sensor/wiki/WikiStart#Buyingguide
With the following additional parts:
1x Dual Relay Module
or
1x Single Relay Module
TOTAL SENSOR PRICE: $7.6 (arduino + radio) + $3.3 (relay module) = $10.9
