Generic 4-Channel 315MHz RF Remote Transmitter (Non-Locking Mode)
A 4-channel wireless RF remote transmitter operating at 315 MHz for momentary (non-locking) control applications. This ASK-modulated, fixed-code unit requires a 12V power source and is designed to interface with compatible 315MHz receivers for DIY automation, remote switching, and microcontroller triggering.
Features
- Four-Channel Momentary Control: Provides four independent button inputs, each generating a high-level output signal on the receiver only while the corresponding button is pressed, ideal for triggering relays or MCU interrupts.
- 315 MHz ASK RF Link: Operates on the license-free 315 MHz ISM band using Amplitude Shift Keying (ASK) modulation with a fixed code encoder for simple, reliable wireless communication over short to medium ranges.
- Compact 12V Transmitter: The handheld remote is powered by a 12V battery (not included) and draws only 10mA during operation, ensuring long battery life for intermittent use in automation projects.
