This PIC16F84 based adapter counts the radioactive particles which is detected by Geiger counter. The result will be displayed at LCD. The first line will show count per second (CPS) or count per minute (CPM) while the second line will show equivalent radiation level. The adapter counts the radioactive particles by connecting to the Digital Output of the analog Geiger counter.
The Digital Meter adapter is one of three adapters. It can be connected to the Digital Output. There is a RS-232 Adapter for connecting the analog meter to a PC. This allows the radiation detected by the Geiger counter to be graphed onto the PC and saved into files.
