1. The AFM3020 sensor is Aoson Electronics' gas flow sensor, which measures the flow of air, oxygen and other non-corrosive gases with superb accuracy.
2. Using 5V power supply voltage, with digital I2C interface. Output measurements are calibrated internally and temperature compensated.
3. Internally, a thermal sensor chip is connected to a high-performance CMOS microprocessor with integrated 24-bit AD acquisition.The gas flow is measured by the thermal sensor chip, ensuring very fast signal processing time and higher accuracy than similar products.
