Product Brief
Puffin is a BLE-enabled logger with built-in environmental and motion sensors. Leveraging BLE, the logger enables easy, fast set up and data download directly to the mobile app. Also, the logger has a micro-SD card provision which helps in logging the sensory measurements for a fixed interval of time. The small form factor and compactness makes the Puffin suitable to deploy in hard-to-reach and limited locations.
