Citizen science: measure radiation and light pollution with your phone.
Open-red is a citizen-science platform that turns your phone into a portable measurement station. Pair it with specialized Bluetooth devices and contribute your data to open scientific projects about the environment. WHAT CAN YOU MEASURE? • Ionizing radiation with RadiaCode: dose rate (µSv/h) and counts per minute (CPM). • Light pollution with Opple LightMaster 3: illuminance in lux. KEY FEATURES • Simple Bluetooth Low Energy (BLE) pairing with supported devices. • Geolocated track recording: walk, bike or drive while your phone logs every measurement. • Background service so you don't lose data when the screen is locked. • Interactive maps with your readings and the community's. • Real-time visualization with gauges and charts. • Open, exportable data: your contributions feed a collaborative map. OPEN AND COLLABORATIVE SCIENCE Open-red is an open project. Every track you record is added to the global community map and helps us understand how background radiation or night-sky brightness varies across your area. Data is indicative and depends on the sensor, calibration and measurement conditions. JOIN THE COMMUNITY Got another device you'd like to see integrated?
