Data collection framework based on the Espruino sensor boards, which buffers data locally over several days in 15-minute segments and collects it over Bluetooth Low Energy (BLE) on base stations nearby for later visualization.
The code consists of a python script that routinely collects sensor data over BLE from nearby Espruino boards, and embedded javascript code on these boards that routinely samples the data. This allows long-term sensor data collection and visualization.
Example 1: Office temperature (left, in degrees Celcius) and ambient light (right), measured by a nearby Puck.js over the past days:
Example 2: Nearby collected Bangle.js data (temperatur, heart rate, steps)
