The Turbinator: A Contact-less Turbidity Sensor Utilizing Laser, Camera and Low Power Neural Network Processing

Explore an innovative 56-minute technical talk from the tinyML Talks France meetup that delves into a groundbreaking patented sensor technology for measuring water turbidity. Learn about a contact-less system that combines laser light scattering photography with advanced neural network processing on low-power hardware. Discover how this sensor, designed for long-term deployment in stormwater wells, utilizes a multi-input, multi-output neural network running on the Greenwaves Technologies GAP processor to analyze water conditions. Understand the technical challenges faced during development, including training data acquisition in real-world scenarios and neural network model quantization for optimal memory usage. Follow AI expert Jens Wilhelmsson's presentation on how the system processes captured images by integrating surface distance measurements to produce both turbidity predictions and reliability indicators, while operating on minimal power with NB-IoT communication capabilities for years of autonomous operation.
