Microprocessor Counter for Geiger-Muller circuits.
       
  EC628 Electronic counter schematics.  

The ideal complement for your Geiger-Muller circuit (Microprocessor controlled)
 
The ideal electronic counter design for your Geiger-Muller circuit. This HobbyChip electronic circuit, PIC16F628 microcontroller program based, counts and display the impulses coming from your radioactivity detection circuit, transforming it into a powerful radioactivity meter circuit, a Geiger-Muller Counter circuit. This electronic kit can be connected to the most part of Geiger-Muller scheme circuits for radioactivity detection. The EC628 is the best complement for your Geiger-Muller counter kit. With the EC628, you will be able to make, from a Geiger-Muller counter kit, an easy radioactivity measurement at very low cost.

EC628 Overview

The EC628 is the perfect complement for circuits than only have a visualization system by needle or/and loudspeaker. With only three connections, the EC628 converts your radioactivity detector in a powerful and versatile Geiger-Muller counter.

The EC628 is a circuit of reduced size and very easy to use. With only a seven segments digit, two Leds, a push-button and a piezoelectric loudspeaker, the EC628 offers very much possibilities to your circuit.

The EC628 can be connected to the most part of radioactivity detector circuits. If you have a Geiger-Muller circuit, or you want to design a new one, connecting the EC628, your system will become a powerful measurement circuit.

The EC628 can count the impulses coming from your detector during periods of time between 1 and 128 minutes. Therefore it can measure with much exactitude the levels of radioactivity.

The EC628 is also used, as electronic counter, by other systems in which you wants to count, during a configurable time period, the impulses produced by a process.

 

HobbyChip EC628 main characteristics 

  • Very easy connection to the radioactivity detector circuits
  • Continuous visualization of measurements level
  • Visualizes the complete number of particles detected (since 0 to 99.999.999)
  • User configurable Count Period Duration (since 1 to 128 minutes)
  • Visual indication (blue LED) and sonorous of each particle detected
  • Low Battery control and indication
  • On/Off control for the particles detector circuit
  • The size of the digit permits it to be seen since long distance
