Interface read data AM2320 serial interface, the sensor signal to read and power loss, have done the optimization. Sensor using a single bus, I2C two kinds of communication output, communication can be free to switch, easy to use. The bus interface determined by the level of SCL line when is powered up

  • SCL remains low for single bus communication mode on power-up;
  • SCL remains high at power-up and I2C communication mode.
  • Single bus is fully compatible with other products of the company's single-bus communication;
  • I 2 C communication protocol in accordance with the I 2 C standard addressing, can be directly linked to the I 2 C bus (bus only allows hanging a product), no additional wiring, easy to use.

Read AM2320 sensor, in strict accordance with the two communication protocols and timing. Detailed communication protocol specific to see a single bus and I 2 C communication protocol detailed page.
