The PMW3901 is a small, low-power optical flow sensor that measures movement by analysing surface patterns. It is widely used in robotics, drones, and automation to estimate position changes without ...

A novel lumped parameter SPICE model for a thermal flow sensor is presented. The model is constructed by 13 circuit cells consisting of thermal resistors and thermal capacitors. The circuit cell ...

Abstract: This paper presents a new temperature compensation technique for thermal flow sensors that are operated in a constant-temperature-difference (CTD) mode by means of a simple analog circuit.
