Arduino driver for the Pixart PMW3901 optical flow sensor. The driver is developed to support the Bitcraze Flow Breakout board. It communicates with the sensor using SPI. The library is using the ...
The analog value from the sensor is converted to distance using either a polynomial fit function up to fifth order or a power fit function. By default, this library is set to use polynomial ...
Abstract: Passive infrared (PIR) sensors, currently used for indoor lighting control report frequent false negative detects for stationary occupancy, which takes up almost 50% of the total occupancy ...
Abstract: In this article, we present the architecture of the wireless sensor network based on nRF24 technology, detailing the communication protocol and data packet structure. Furthermore, we ...
