This reference design is an analog front-end for an advanced motion detector based on two PIR sensors for false trigger avoidance, enabling machine learning. This design has a standard BoosterPack™ pinout, uses Texas Instruments low-power components, and runs on one AAA alkaline battery cell.
The PIR_MOTION GUI helps to run faster the data acquisition and visualization from the reference design through a number of graphs and allows control of certain parameters. It shows in real time the PIR sensor data and the wavelet transform (CWT) as well as the humidity, temperature and light sensor data.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
