It is commonly used in DIY home automation and hobbyist electronics projects.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I pair a remote control with this receiver module?\u003c\/h4\u003e\n\u003cp\u003eA: The module supports the 1527 learning code format. Simply press the onboard learning button to enter pairing mode, then press the desired button on your 433MHz remote control. The module can store up to 10 different remote controls, making it flexible for multi-user setups.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between Momentary, Toggle, and Latching modes?\u003c\/h4\u003e\n\u003cp\u003eA: In \u003cstrong\u003eMomentary\u003c\/strong\u003e mode, the relay is active only while the remote button is held. In \u003cstrong\u003eToggle\u003c\/strong\u003e mode, each button press alternates the relay between ON and OFF. In \u003cstrong\u003eLatching\u003c\/strong\u003e mode, the relay stays in its last state (ON or OFF) until commanded otherwise — ideal for standard light switch behaviour.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the wireless range of this receiver module?\u003c\/h4\u003e\n\u003cp\u003eA: In open areas with no obstructions, the module typically achieves a range of 30–50 metres. Walls, metal objects, and other physical barriers may reduce this range. Repositioning the module or remote can help maximise wireless performance.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What devices can I control with this 433MHz RF relay receiver module?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This module is ideal for controlling DC-powered devices such as LED lamp strings, Christmas tree light strings, and other low-voltage lighting or switching applications operating within DC 3.6V–24V.
