Arduino Geiger Counter

Step 1: What you will need

What you'll need:
-Arduino (Can be any type but must have 5V capabilities to work with Geiger counter and LCD)
-Sparkfun Geiger Counter (Other geiger counter boards might work the same but I do not know)
-LCD display
-LED
-Piezo Buzzer
-9V Battery & Battery Clip
-Slider switch
-Project Box ~ (129mm*64mm*45mm)

Hey just asking again could i use this: http://www.ebay.com/itm/Assembled-DIY-Geiger-Count...

Instead of the spark fun geiger counter? THX

Yes, that should work fine

Nice work! Just asking what wires do we use for step 2?

iBooky (author)  Star31610 days ago

Thanks! The VCC, 5V and GNDs are to power the geiger counter and LCD display while TX and RX are what the Arduino uses to receive information from the Geiger tube and transmit information to the LCD display.

Thanks! Followed you! :) 3rd follower! :3

Could i also use the arduino uno instead of the mini?

Yes, just make sure your project box is big enough to fit the Uno

Thank you, it displays a counts per minute instead of counts per second. Measuring half life would be pretty cool and I haven't tried that yet, thanks for the suggestion.
nice work. i would have some idea of how to make the detection apparatus of the geiger-marsden tube but very well done on building a system that appears to give you a counts or counts per second(becquerels) reading. you may wish to use it to measure the half life of the source in a smoke alarm but unless it is a very sensitive system you will have to wait a long time(432 years for the count rate to halve but some calculations based on A=A0 x e^(-L x t) would allow a measurement of the half life without waiting so long.).
