C-GM Counter - Connected Geiger-Müller Counter
by AdNovea (c)2018-2019
C-GM Counter is a very low cost Ethernet DIY Geiger-Müller counter (radioactivity).
The overall A-GM project is aimed for providing a long-term continuous measurement of the radioactivity level. It is made of an open-source Web application running on a SOHO server (e.g. QNAP sells Small Office Home Office servers) connected to a C-GM Counter device or a compatible GMC-320 Geiger-Muller Counters from GQ Electronics LLC. Other compatible or DIY Geiger-Muller counters could also be used. This project has been developed and is provided AS IS by AdNovea®.
C-CGM Counter: - Device (counter) hardware and firmware for recording radioactivity levels compatible with A-GM Manager. (https://sourceforge.net/projects/c-gm-counter/)
A-GM Manager: - A web application for long-term continuously monitoring and storing on local servers the Beta/Gamma radiation levels acquired from Geiger-Muller Counters. (https://sourceforge.net/projects/a-gm-manager/)
DEVICE SPECIFICATIONS (preliminary)
- Radiation detection : beta, gamma, X-ray
- GM tube : STS-5 (CTC-5) / SBM-20 (400 V operating voltage)
- Language support : English only
- Maximum value 65 535 CPM / 425 µSv/h (theoretical)
- Display values : Current CPM, Current µSv/h, Maximum µSv/h since startup, Average µSv/h since startup, Elapsed time since startup, Level on bar graph
- Alarm: User defined threshold, LCD backlight blinking, Alarm messages on LCD
- LED flash for each beta/gamma radiation pulse: LED blink every second if GM tube is detective, LED still on when Network connection fail
- Audio sound: Beep for each beta/gamma radiation pulse, Audible sound alarm
- Device control from : Device internal menu, USB (require a serial console such as Termite) or Ethernet (using a web browser)
- Network connection using DHCP
- Support for A-GM Manager web interface
- User defined parameters (from Menu or through web interface)
- GM tube conversion factor (CPM to µSv/h): Alarm threshold in CPM, Buzzer On or Off, Display timeout, Enable Network for communication to A-GM Manager, A-GM server IP definition (through USB or A-GM Manager), Internal H.V. voltmeter calibration (through USB or A-GM Manager),
- Connect to A-GM Manager for storing data and graphic display.
- Parameters can be permanently saved into EEPROM
Physical Parameters:
- Ethernet and USB ports
- Size (L x W x H) : 158mm x H: 90mm x D: 60mm
- Net weight (w/o battery): 76 g
- Total weight: 315 g (w/o probe, cable and DC pack)
- Power: 5V DC pack (~2Watts)
- Interface: English only
NOTES: Network is disabledd after flashing the device for easy configuration through USB port. This will avoid the network to hang due to improper DHCP initial configuration.
IMPORTANT: Since v1.4, Arduino Nano MUST BE FLASHED with the OptiBoot bootloader. With the ATmegaBOOT bootload, device will keep rebooting indefinitely !!!
