There is an iPhone/iPod app and I believe an Android app is out or planned. It would make a good Arduino attachment too to read out onto an LCD or post readings via ethernet or WiFi. Their goal is to have a product out this Fall for ~$50 US with $20 shipping. Circuit to fit in a Dutch mint tin with external 9v.Project
We are international, volunteer team of engineers, designers and scientists. We believe that everyone – children, students, mothers, senior citizens, anyone – has the right to know the correct radiation level especially in and around nuclear power plants. Information regarding radiation should be readily available, just like the temperature outside or the weather.
Specifications
Sensor: PIN photo diode x8 (reverse biased and shielded)
Detectable radiations: Beta and Gamma radiation
Sensitivity: 0.5uSv/h -> 124cpm (without beta radiation shield)
Software features: CPM, uSv/h (currently under development) and Oscilloscope
Dimensions: about W55mm x H28mm x D8mm (except case, battery, DC line and phone plug)
Power consumption: about 1mA
Battery: 006P/9V (outside of the case)
I wrote Naomi about posting this and she asked for good feedback. This is the place Anyone with ideas that would help them please contact them.
