I found no appreciable difference in the average between counting for 1 minute, or 15 seconds and 5 seconds.#define LOG_PERIOD 15000 //Logging period in milliseconds, recommended value 15000-60000.#define MAX_PERIOD 60000 //Maximum logging period without modifying this sketchunsigned long counts; //variable for GM Tube eventsunsigned int multiplier; //variable for calculation CPM in this sketchunsigned long previousMillis; //variable for time measurementvoid tube_impulse(){ //subprocedure for capturing events from Geiger Kit multiplier = MAX_PERIOD / LOG_PERIOD; //calculating multiplier, depend on your log period attachInterrupt(0, tube_impulse, FALLING); //define external interrupts Serial.println("Start counter"); // code I addedvoid loop(){ //main cycle#define LOG_PERIOD 15000 //Logging period in milliseconds, recommended value 15000-60000.#define MAX_PERIOD 60000 //Maximum logging period without modifying this sketch#define PERIOD 60000.0 // (60 sec) one minute measure periodvolatile unsigned long CNT; // variable for counting interrupts from dosimeterunsigned long counts; //variable for GM Tube eventsunsigned int multiplier; //variable for calculation CPM in this sketchunsigned long previousMillis; //variable for time measurementunsigned long dispPeriod; // variable for measuring time// initialize the library with the numbers of the interface pinsattachInterrupt(0,GetEvent,FALLING); // Event on pin 2lcd.setCursor(0,0); // print text and CNT on the LCDif (millis() >=dispPeriod + PERIOD) { // If one minute is over
The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.Geiger counter at work (copy the following link to the browser to watch): Http://v.youku.com/v_show/id_XNzI3MTU2NzQ0.htmlConnect P3 GND, 5V, VIN to Arduino GND, 5V, Digital 2 respectively.Then in the arduino IDE software open the file: spi_rad_logger.ino which you could find Be sure to change the Serial.print(cpm) command to Serial.println(cpm) in the void loop(){} for better readability.Upload the program onto the board. After I read the data sheet of the philips 18505 and SBT-9, I think that i'll chose SBT-9 for the next tube.

2.00 RH-K-GK-2-A with UART logging. 9 months ago INT connected to pin#12, 5V to pin#2, GND to pin#6. As for every decent project you will also need lots of hot glue, some wire and a soldering iron.
Thanks First test with extern USB 5V: I can hear the pings.
9 months ago This is updated version 2.00 of our simplest Geiger Counter project based on Arduino IDE.

Winkel met vertrouwen. You go on line and try to duplicate how others have connected their Geiger counter to Arduino only to find something is wrong. Other than the obvious differences for the serial LCD I powered my geiger counter off my Uno not a power supply.
But, I don't know where is katode or anode. As long as you downloaded the Libraries.

Also designed a custom PCB for it, …
I have been wanting to build a Geiger counter for a long time to complement my As you can see in the video the counter reacts to radioactivity with audible clicks from a piezo buzzer. I don't know the the Arduino code but this is what I have. For the final build I needed a smaller tube though so I bought an SBM-20 which came wrapped in Ukrainian newspaper and included a discount coupon for a Chernobyl tour The picture shows a larger 1.8″ LCD display which I plan to use for another projectThis generates the 400 V necessary to operate the Geiger tubeSince current drawn from the tube is negligible the module needs only be able to provide ~100 mA for the Arduino and display.Make sure to get the one with discharge protection that have separate ‘B+/-‘ and ‘Out+/-‘ pinsI prefer the branded ones like LG since I do not trust a battery whose name contains the word ‘fire’.These are for holding the tube so you do not have to solder it directlyIn addition, I used black and silver acrylic paint for the housing. 4 months ago 5 weeks ago Het aantal biedingen en de bedragen zijn mogelijk nog niet helemaal bijgewerkt.
