Product Attributes

Introduction

SRX885 is a micro-power receiver module that employs RF superheterodyne demodulation, compatible with STX series ASK transmitter modules. This product offers high stability, strong interference immunity, and excellent cost-effectiveness, while also featuring four-channel digital switch output functionality. Flexible in application, it is characterized by low cost, zero development and debugging required, built-in decoding, adaptive support for various encoding schemes, and automatic learning of commercially available RF remote controllers. It is widely used in lighting control switches, wireless doorbells, smart home systems, rolling shutters, remote-controlled toys, burglar alarm systems, and more. The module can obtain certifications including RoHS, FCC, and CE. SRX885 is strictly manufactured and tested using lead-free processes, compliant with RoHS and REACH standards.
