How to make your Mica power efficient
By performing the following modifications, your Mica will be able to run the
low power Snooze component in TinyOS which puts your Mica to sleep. In sleep mode, the Mica consumes ~50-75uA.
You will need:
- Wire wrap to connect the diode to C9
- Soldering Iron and Solder
- Diode (available from Digikey as part # BAT54C by Diodes Inc.)
First place solder over the two connections of R31. Bridging this bypasses a diode that that battery voltage would otherwise go through.
Solder the diode to the large reservoir capacitor, C5. Solder the wire wrap to the other side of the diode. Then solder the wire wrap to the positive
side of C9. Lastly, remove R29. You're done!
Now you can install the nesC TestSnooze component. Be sure to program the "little guy" with LG_sleep for maximum current conservation in
sleep mode.
