SRX885 : 315/433MHz ASK Receiver Module With Multi-function Decoding
SRX885 is a micropower consumption 315/433MHz ask receiver module with RF superheterodyne modulation. It can be used with our STX series ASK transmitter module. This product has high stability, anti-interference and high cost performance, and also has a four-way switch output function. It is flexible to use, low cost, development-free debugging, self-decoding, adaptive coding, automatic learning of the market RF remote control. A large number of applications in light control switches, wireless doorbells, smart homes, rolling gates, remote control toys, anti-theft alarm and other fields. The modules can pass ROHS, FCC, CE and other certifications.
