Using Multiple Geiger Counters with my Adafruit Build

Post by nluogameno »

Hello,

I am using DFRobot's Gravity Geiger Counter for a project that includes a few Adafruit sensors. I'd like to use two of the Geiger Counters at the same time. One will be used as a control to see what regular radiation levels are, and the other will be covered with a material to block radiation. I'd like to compare readings from both to see how well the material is working at blocking radiation.

I feel like it is probably a simple solution to read from both sensors at the same time, but I'm not sure what I need to change in the sketch to make this work. Also, I imagine that I'd have to plug each sensor into a separate pin on the Arduino. The default pin to use is D3. Based on the following code from DFRobot, what should I edit to make two Geiger sensors work at the same time. I'll then add the edited code to my larger project code that includes the Adafruit sensors.


Code: Select all

#include <DFRobot_Geiger.h>

#if defined ESP32

#define detect_pin D3

#else

#define detect_pin 3

#endif

/*!

u/brief Constructor

u/param pin External interrupt pin

*/

DFRobot_Geiger geiger(detect_pin);


void setup()

{

Serial.begin(115200);

//Start counting, enable external interrupt

geiger.start();

}


void loop() {

//Start counting, enable external interrupt

//geiger.start();

delay(3000);

//Pause the count, turn off the external interrupt trigger, the CPM and radiation intensity values remain in the state before the pause

//geiger.pause();

//Get the current CPM, if it has been paused, the CPM is the last value before the pause

//Predict CPM by falling edge pulse within 3 seconds, the error is ±3CPM

Serial.println(geiger.getCPM());

//Get the current nSv/h, if it has been paused, nSv/h is the last value before the pause

Serial.println(geiger.getnSvh());

//Get the current μSv/h, if it has been paused, the μSv/h is the last value before the pause

Serial.println(geiger.getuSvh());

}
