433MHZ 4 Button RF Wireless Remote Control For Light / Door / Alarm System

SYA0020611
1. Non-directional, the characteristics of wireless remote control are non-directional, non-face-to-face control, long distance (It can reach tens of meters, or even several kilometers), which is very suitable for long-distance penetration or non-directional control fields, such as garage door remote control, industrial control etc.
2. The coding capacity is large, the number of address codes is greater than 100,000 groups, and the probability of recode is extremely small when using.
3. The code is easy to match, the rolling code has the function of learning and storing, without using a soldering iron, the code can be matched at the user's site, and a receiver can learn up to 14 different transmitters, which has a high degree of flexibility in use.
4. Strong confidentiality, the code is automatically changed after each launch, others cannot use the code detector to obtain the address code.
5.The probability of error code is small. Due to the advantages of coding, the error action of the receiver when it does not receive the native code is almost zero.
