Arduino / Sanguino Microcontroller Prototype Programmer for iButton Dataloggers

For Source Code see:

http://arduinofun.blogspot.com/

This is a video demonstrating a prototype programmer for Maxim's iButton temperature and humidity data loggers. The programmer can start / stop data logging missions and read the latest data point in the field without a laptop!

The programmer uses a microcontroller called Sanguino, which is a more powerful clone of the popular Arduino microcontroller. See http://sanguino.cc/ for more info.

The 16x2 LCD is from Newhaven running in I2C mode and was purchased from fungizmos.com.

The button debounce IC is Maxim 6818. It can handle up to 8 buttons!

See this video for a great tutorial on surface mount soldering:

Real time clock is a DS1994 iButton. Supported sensors include: DS18S20, DS1921G, and DS1923 temperature and data loggers.

Next step is to clean up the code and make a usable device for use in the field!

The atmega328 was not available when I was developing the code.

Is the i-button pre-programmed or did you program it?

[jmarduino]

The i-button data loggers have onboard clock, memory, temperature, and / or humidity sensors. My programmer starts the clock, reads current value, and starts / stops data logging missions.

LOL

Your voice sounds so 80's movies in this vid, the noise also helps a bit.

Can you help me to develop I button reader to use in WIP monitoring? It is basically integrating many reader units connected wih CAT5 cables having RS485. Then RS485 should be converted to RS232 and connect to the PC. The reader is to record movement of material from one place to another. Can you help me on this?

I have seen security guards at malls use something like this. Every corner of the mall had a metal button that they would touch something against when they did their rounds.

Guess its to make sure they are doing there not just staying in one place.

Very impressive!
