sleeping at 300ms, it would receive the Beacon package from AP after each 3ms, then the whole average
current is about 0.9mA.
③
Deep-Sleep mode is applied to the case that Wi-Fi is not necessary to connect all the time, just send
a data packet after a long time (e.g., transmit one temperate data each 100s) . it just need 0.3s-1s to
connect AP after each 300s, and the whole average current is much smaller 1mA.
6. Wi-Fi RF Characteristics
The data in the following Table is gotten when voltage is 3.3V and 1.1V in the indoor temperature
environment.
