It’s funny how even early experiences change the way you think about a design. Two minor changes to SleepySketch have been suggested by early testing.
A simple radio survey establishes the ranges that the radios can manage.
Keeping the microcontroller asleep as much as possible is a key goal for a sensor system, so it makes sense to organise the entire software process around that.
The Arduino has several sleep modes that can be used to reduce power consumption. The most useful for sensor networks is probably the one that uses the watchdog timer.
Probably the definitive hobbyist’s description for small-scale sensor networks.
Any sensor network has to represent sampled data somehow. What would be the most friendly format for so doing?
Temperature sensing using digital temperature sensors is easy to get working.
The DS18B20 is a programmable digital thermometer that needs no calibration and uses only one wire of the microcontroller.
A small sensor network now working, with two edge devices talking to a base station.
A library for using XBee radios with Arduinos.
