DFRobot F1031V Mass Air Flow Sensor detects the flow rate of a gas medium in the flow channel using thermodynamic principle with high-precision and good repeatability. This device offers completely calibrated and temperature compensated measured data by incorporating a built-in temperature sensor. The F1031V airflow sensor provides a linear analog voltage output for easy understanding. Typical applications include ventilators, air purifiers, industrial process control, and environment protection.
