From the shop's description

4-Channel RF Wireless Remote Control Module 315MHz | Non-Locking | 12V Transmitter + 5V Receiver Upgrade your wireless control projects with this 4-Channel RF Wireless Remote Control Module. Operating at 315MHz, it features a four-button handheld transmitter paired with a highly sensitive receiver module. The non-locking (momentary) mode ensures the signal is active only while a button is held – ideal for devices requiring temporary triggers such as electronic door locks, alarms, and smart control systems. Each button on the remote corresponds to one of the receiver’s output pins (D0–D3), providing precise and responsive wireless control . The module is compatible with microcontrollers like Arduino and Raspberry Pi, making it ideal for students, hobbyists, and industrial developers. Features: 4 separate control channels 315MHz RF communication 12V transmitter, 5V receiver Non-locking momentary output Compact receiver module (41x22x7mm) Receiver sensitivity: -98dB Signal range: 3 to 5 meters (open space) Easy connection: VT, D0–D3, +5V, GND, ANT Applications: Remote-controlled lighting Wireless signal triggering Door locks, electric gates, alarms Arduino and IoT applications Note: Battery not included due to air shipping restrictions.
