Description and architecture
In this systems, the sensors are read under interrupt, while some low-speed processes are executed under a 1 sec repetitive timer. The interrupt rates vary, from a few tens of ms (light measures) to completely arbitrary rates (motion detection) or very long periods (Heart Rate value). Hence I had to defined software components at 2 layers Continue reading “Sensor Fusion controller using Fuzzy Logic approach (software implementation)”
Following the previous article, I now concentrate on design choices and implementation.
The device was an OHRM gadget, so there was already some sensors available which could be used: Continue reading “Sensor Fusion controller using Fuzzy Logic approach (Design choices)”
The recent rise of MEMS and Microsensors have posed a new and interesting problem to designers. Before MEMS, you barely had one temperature sensor, maybe one pressure sensor in your system. Then you would put some code around … Et Voila ! your device was capable of measuring Temperature and Pressure. Continue reading “Sensor Fusion controller using a Fuzzy Logic approach (intro)”
