Wireless Data Transceiver, 433Mhz RF Module

NOTE: Generally the module is in receiving status, if the Sleep pin (No.8) continuously connects low level
(>200millisecond), the module will be in sleep status, modules can not receive or transmit any data when sleep.
Only when the Sleep pin set in the state of high level (VH<3.5V) or hangs/empty, module can be in receiving
status again. The delay time for conversion between sleeping and receiving is less than 150mS.
