This 4-button keyfob remote is a perfect match for our three basic 315MHz RF receiver modules. It can send four different commands corresponding to four outputs. Small and lightweight, it has a working range of up to 25 feet, depending on line-of-sight and obstructions. As a transmitter, it can turn on and off multiple receivers simultaneously (no sub - addressing). Note that a matching RF receiver is not included and needs to be purchased separately.
How to use: First, make sure your 315MHz RF receiver module is properly installed. Then, just press one of the four buttons on the keyfob to send a command. The receiver will respond accordingly. Note: This keyfob can control multiple receivers at once. However, there's no sub - addressing feature. If you have different receivers that need separate control, this might not be suitable. Also, the working distance of up to 25 feet depends on whether there's a clear line - of - sight and any obstructions. Maintenance: Keep the keyfob clean and dry. If the battery runs out, replace it with a new one of the same type.
