In Episode 2, we talked about<\/em> Module DCDC_3V3_400V – step-up voltage converter for Geiger counter with pulse output<\/strong><\/a> .<\/a><\/em><\/p><\/blockquote>\n\n

GGreg20<\/strong> – one of the boards for amateur production (DiY) of radiation level dosimeters. This board includes the following functional units:<\/strong><\/p>\n\n

  1. The main power supply unit of the module – connectors, switch, mode switch (jumper) and linear stabilizer. This node is built so that the recorder can act as a master – slave power supply in relation to the controller.<\/li>
  2. The high voltage Geiger-Mueller tube is supplied by the DCDC_3V3_400V module, which is mounted on the GGreg20 board.<\/li>
  3. To mount the Geiger-Mueller tube on the GGreg20 board, three holders are soldered, on which you can install two types of tubes – SBM-20 (SBM-20) or SI-3BG. A number of SMD components provide a mode of powering the tube and removing pulses from the tube according to the number of particles entering the tube.<\/li>
  4. The board has a buzzer and an LED for the possibility of autonomous use of the board as a radiation level detector. These alarms display data that allow you to calculate the level of radiation per unit time.<\/li>
  5. The board has components designed to match the level of information pulses in accordance with the input requirements of the GPIO controller.<\/li><\/ol>\n\n
