DFRobot - FRn20-H0D Mass Air Flow Sensor

The FRn20 gas flow sensor adopts the MEMS thermal principle to measure the flow rate of gaseous media inside pipelines. Boasting high sensitivity and an ultra-low startup flow rate, it supports optional I2C or analog voltage output with excellent full-scale stability and repeatability. It is applicable to ventilators, air purifiers and other related equipment.
