Open Source Geiger Counter Kit for Arduino with RealTime Radiation Feedback, Visual Alerts, Gamma Beta Detection

Nuclear Radiation DIY Detector Kit A compact, Arduino compatible Geiger drive kit with visual and audible indication of radiation. Designed for MCU developers and hobbyists who want a ready PCB to drive common Geiger tubes and integrate into an Arduino COSM monitoring station or similar logging setup. Key benefits Immediate detection feedback: visual LED and audible click output for realtime indication of detected pulses. Developer friendly: includes a PDF manual with assembly instructions and Arduino code examples to accelerate prototyping and integration. Ready for integration: SPI compatibility with Radiation Logger via Arduino makes remote logging and networked monitoring straightforward. Flexible tube support: PCB can drive M4011, STS5, SBM20, or J305 Geiger tubes, letting you use the tube suited to your application. Compact and portable: small Geiger tube dimensions simplify mounting and enclosure design. Main functions and performance Detects both gamma and beta radiation.
