RAD-S50 Radon Gas Sensor — Precision Silicon Detector for Continuous Indoor Radon Monitoring

Shenzhen, China — The RAD-S50 is a high-performance radon gas sensor module engineered by Wanyi Technology (brand: CESTSEN) for long-term continuous monitoring of radon concentration in indoor environments. Featuring a large-area silicon detector with static diffusion sampling, the RAD-S50 delivers reliable measurements across a wide dynamic range from 5 to 65,535 Bq/m³ with exceptional sensitivity of 0.027 cph/[Bq/m³].

RAD-S50 Radon Gas Sensor Silicon Detector 5-65535 Bq/m³ Static Diffusion UART I2C Output Indoor Monitoring

Product Overview

The RAD-S50 radon detector measures radon gas concentration through the principle of static diffusion. By leveraging the radioactive properties of radon gas and its decay products, the sensor acquires alpha counts via a high-performance silicon detector (100mm² sensitive area, 10*10mm) and an advanced signal acquisition system. The integrated algorithm calculates precise radon concentration values, achieving continuous, unattended environmental monitoring with minimal power consumption.

Application Fields

Indoor Radon Measurement: Continuous static radon monitoring in residential, office, and public buildings for health risk assessment.
Environmental Radiation Monitoring: Long-term background radon surveys in geological, mining, and construction sites.
IoT Sensor Networks: Integration into wireless sensor nodes for distributed indoor air quality monitoring systems.
Laboratory Research: Radon gas behavior studies, material emission testing, and calibration reference measurements.
Smart Building Systems: Embedded radon sensor for active HVAC control and ventilation optimization in green buildings.

Why Choose RAD-S50?

The RAD-S50 stands out with its exceptional balance of high sensitivity, ultra-low power consumption, and compact design. Unlike pump-based radon monitors that require regular maintenance, the passive static diffusion method ensures years of trouble-free operation. The dual UART/I²C interface provides plug-and-play compatibility with popular MCU platforms including Arduino, ESP32, STM32, and Raspberry Pi. Adjustable parameters allow customization of measurement intervals, alarm thresholds, and data output formats to meet diverse application requirements.

Packing & Delivery

Each RAD-S50 sensor module is packaged in an anti-static protective bag with foam cushioning and shipped in export-grade corrugated cartons. Minimum order quantity: 1 piece. Supply capacity: 5,000 pieces per month. Delivery time: 3-10 working days. Payment accepted via T/T, For bulk orders, OEM customization, or technical inquiries, please contact Wanyi Technology (Shenzhen, China).
