RadMonPlus

Currently this is a personal project, and I do not have kits for it. However if you want a simple way to hook the Geiger Kit to the internet see the GKnet project. Kits are available for that.

This project merges the features of two others - the RadMon project, where data from the outside sensing unit is sent to an inside display station and the GKnet project where CPM data is posted to sites on the internet via a wired LAN connection.

In addition, I wanted the display station to connect to the internet using WiFi, and rather than using a 2x20 LCD for the inside display I wanted to use a color graphic display.

To do this, there is one major obstacle - program space, the final frontier. As it is, the original display station barely has enough RAM (32k) to hold the libs for the RFM22, SD card, RTC, and LCD display. The solution was use a bigger chip. Currently, I'm using an ATmega644P (64k), but a ATmega1284P (128k) could also be used. Both are 40 pin DIP with the same pin-outs, and are compatible with the Arduino IDE.

I used this TFT 1.8" color LCD from Adafruit and this WiFly board from Sparkfun accessed with a very nice library - WiFlyHQ.

I already had a 644P/1284P development platform that I made some time ago. I added a "shield" for it to hold the "sensing unit" PCB with the RFM22, the WiFly, and a level shifter for the RF22.

So "RadMonPlus" is receiving data from the sensing unit via RF, displaying it on the color LCD, and sending it on to Xively, data.Sparkfun.com and Radmon.org via WiFi.

You can see the updates to Xively here Since the sensing unit also has sensors for temperature, humidity, and barometric pressure, that data is sent as well.

You can see the output to Radmon.org here. That site allows you to compare your data with sensors around the world. (see map)

You can see the updates to data.sparkfun.com here It also sends temperature, humidity, and barometric pressure as well.
