The Type 5 Pocket Geiger Radiation Sensor from Radiation Watch is a highly sensitive radiation sensor designed for the embedded systems market. Capable of detecting Gamma and Beta radiation, this sensor has a simple pulsed output that can be used with any microcontroller. Radiation Watch has a handful of documents and example Arduino code to get you up and running. They have also written a Windows example program in C# (source included!) to output graphs to a computer using an Arduino as the reader.
These small Geiger sensors feature a measurement range of 0.05uSv/h to 10mSv/h at 0.01cpm to 3..
You talked, we listened, and we’ve revised our Geiger Counter board to address some of the most pressing concerns. This version features an improved voltage regulation circuit for the Geiger tube which has a much cleaner output. We’ve also modified the signal capture portion of the board so that it reads active high, allowing for more dependable counts that are less susceptible to fouling due to line capacitance. The new signal capture circuit also pushes the CPM limit to 100Hz!
This USB powered SparkFun Geiger Counter is equipped with an ATMega328 that can be programmed in circuit using one..
Need to test for nuclear fallout? Geiger tubes are the sensing elements of Geiger counters, which are used to measure ionizing radiation. This tube is made of a thin-walled stainless steel and is filled with a mixture of Neon and Halogen gases at low-pressure.
You’ll need a large voltage to get the Geiger tube to going - 325VDC minimum, 500VDC recommended. If ionizing radiation passes through the tube, short pulses of current will flow from the negative electrode to the positive electrode to be measured or counted. Check out the datasheet below for an application circuit.
