Using Arduino with Ada

Wireless temperature sensor using Olimexino-328, XBee, and DS18B20

I have made temperature sensor in the past, but now I added power saving features to the code.

The result was a device which lasts almost a month when it reports temperature once an hour over XBee and is powered by 1000mAh LiPo battery.

Instead of official Arduino, I used ...

Temperature measurement with DS18B20 and one-wire protocol

Required parts:

  • Arduino UNO or Duemilanove
  • DS18B20 temperature sensor
  • Some jumper wires
  • About 5K ohm resistor (4.7Kohm or 4.99Kohm is ok)

I had a couple of extra DS18B20 temperature sensors lying around, so I was interested in communicating with them using Arduino.

DS18B20 uses 1-wire protocol for communication ...
