Parameters: 

• Working Frequency:433Mhz / 315MHZ 

• Receiving Sensitivity:-110dBm 

• Working Voltage:3.3V-5.5V 

• Working Temperature:-30-85℃ 

• Size:28X12.5X5mm(L*W*T)

Instructions:

• Jogging:Both T1 and T2 do not connected, when there is signal input, the module will output the corresponding signal. 

• Self-locking: T2 connect with the ground,T1 do not connect. 

• Interlocking: T1 connect wiht the ground, T2 do not connect. 

• Signal indicaotor: when there is signal input, the VT output high level, when signal disappear, VT output low level. 

• Code matching: press the"learning key" and last 2s,the learning indicator will light up, now step into the learning mode,then release the learning key, press the any key, the indicator will flash 4 times,the learning has finished, exit the learning mode. 

• Code match clearing:keep press the learning key,the indicator will always light up,after 8 seconds the indicator will turn off, the code has been cleared.

Pin instructions:
