Interfacing Connection Diagram To interface the PMW3901 sensor module with ESP32, we use SPI communication. Since we had the Pimoroni PWM3901 module, we have used that, but the connection is a ...

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 ...

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. The ...
