6. Electrical Characteristics
Electrical characteristics, such as high energy consumption, low level, input and output voltage,
etc., depending on the power supply. Table 3 details the AM2320 electrical characteristics, if not
marked, it means that the power supply voltage of 5V. If you want to get the best results with the
sensor, please designed in strict accordance with please and conditions in Table 3 and Figure 27 and
Figure 14 Design.

① This accuracy is tested at the factory, and the
sensor at 25
℃ precision ind
conditions tested, it does not include hysteresis and
non-linear, and only suitable for non-condensing
environment.
② At 25
℃ and 1m
