Product description What it does Compact radiation detector with an interrupt output interface that can be connected to a microcontroller and displayed on an LCD. Provides a sound and light alarm for immediate local notification when thresholds are reached. Key specifications (as supplied) Detection ranges: Gamma rays: 20 mR/h to 120 mR/h Soft beta rays: 100–1800 (variation/spot/cm 2) Interfaces: Interrupt output interface for microcontroller connection and LCD display. Alerts: Sound and light alarm. Power options: 5 V DC supply, or three 1.5 V batteries, or four 1.2 V batteries. Current consumption: 12 mA to 30 mA. Why customers need this product Real-time monitoring: Interrupt output lets a microcontroller respond immediately to events and update an LCD for visible readout. Immediate alerts: Built-in sound and light alarm provide instant local warning without needing external systems. Flexible power and deployment: Multiple power options (5 V supply or battery) make the unit suitable for fixed installations or portable use. Clear detection ranges: Covers practical gamma and soft beta ranges for spot checks and basic radiation monitoring tasks. What makes it stand out Integration-ready interrupt output simplifies connecting to embedded systems and data loggers. On-board audible and visual alarms reduce the need for separate warning equipment. Low current draw (12–30 mA) supports battery operation for field use. Practical use scenarios Laboratory and workshop spot checks: Portable monitoring of work areas and equipment where gamma and soft beta presence must be checked quickly. Field surveys and inspections: Battery-powered operation and local alarms enable short-term environmental checks and on-site safety assessments. Embedded projects and automation: Connect the interrupt output to a microcontroller to log readings, trigger external systems, or display values on an LCD for integrated monitoring solutions. Notes and recommendations Use the interrupt output to integrate with your microcontroller firmware so that detected events are processed and displayed on the LCD in real time. Choose the appropriate power mode (5 V supply or recommended battery configuration) based on deployment duration and portability needs. Verify installation, calibration, and operating procedures per your safety and regulatory requirements before use.
