The project integrates CERN’s ACCURATE ultra-low current measurement ASIC into Lightricity’s Lightbox, a portable indoor light simulator for testing PV-powered devices. This upgrade replaces the need for bulky, expensive source meters, enabling compact and low-cost performance evaluation of energy-harvesting components and IoT devices under realistic indoor lighting. By combining CERN’s sensing expertise with Lightricity’s high-efficiency photovoltaic technology, the project supports wider adoption of battery-free, sustainable IoT solutions.

Application areas:

• Evaluation and benchmarking of PV-powered IoT devices (e.g., wireless sensors, trackers)

Key features:

• Ultra-low current measurement (ACCURATE ASIC): Nine-decade dynamic range without band switching, down to 200 attoamperes
• Compact and affordable: Eliminates the need for laboratory-grade source meters (>€6k)
• Flexible and modular: Simulates a wide range of indoor light levels (50–50,000 lux) with multiple light sources
• Scalable impact: Expands access to PV testing tools beyond research labs to commercial developers and educators
