Introduction

The S5019 mass air flow sensor is made of microelectromechanical systems (MEMS) flow sensing chip. It is suitable for clean, relatively dry gas flow measurement and process control for various purposes. 

The unique packaging technology allows the product to meet different ranges of flow measurement, ensuring high sensitivity, high reliability, high stability and low cost.

S5019A is based on a MEMS flow sensing unit and a high-precision digital processing and calibration circuit (MCU). The integrated delta-sigma A/D converter, logic circuit with internal calibration function and MCU processor together ensure that the sensing signal is real-time Effectively collect, obtain accurate flow signals, and perform corresponding compensation algorithm processing internally,

so there is no need to perform any external calibration compensation to ensure high-precision flow output; Friendly digital output communication method, users can easily communicate and obtain corresponding data information.
