7.1 AM2321 pin assignment
Table 4: AM2321 pin assignment
Pin Name
Description
1 VDD
Power supply(2.6 -5.5V)
2 SDA
Serial data, bidirectional port
v3 GND
Ground
4 SCL Serial clock input port (single bus ground)
7.2 Power supply pin (VDD GND)
AM2321 supply voltage range of 2.6V - 5.5V.
7.3 Serial clock input (SCL)
Figure 4: AM2321 wiring diagram
The SCL pin is used to communicate the choice and I 2 C sensor communication clock line.
When the power is held low while SCL remains low even 500ms, which means that the user selects a
single bus mode of communication, otherwise I 2 C communications; After selecting the formula
mode during power, sensor communication mode remains unchanged; If you want to change
communication, re-power on, press the select operation requires communication.
When choosing the I 2 C communication between microprocessor and AM2321,SCL for the
synchronous communication.
7.4 Serial data(SDA)
SDA pin is three-state structure for reading, writing sensor data. Detailed Description of specific
communication sequence, see communication method..
8. I 2 C and a single bus
AM2321 serial interface, and power consumption reading sensor signal aspects are optimized
processing. Sensor uses a single bus, I 2 C outputs two communication modes, communication can be
switched freely, easy to use. SCL bus signal line to level when power to determine their bus
communication: SCL is held low on power as a single bus communication mode; SCL remain high
when compared to the power of communication modes I 2 C. Single bus is fully compatible with the
company's other products, single-bus communication; I 2 C communication in accordance with
