Commanding four independent electrical paths, the 4 Channel Wireless RF Remote Control Module Tx Rx Kit utilizes 315-433 MHz radio frequency. Operating at 5-12V DC, the receiver interprets signals across a 50 to 100-meter line-of-sight range. Logic-level TTL outputs connect directly to microcontrollers or relay boards for remote switching.
Key Features
- 4 Independent Channels: Via the 315-433 MHz frequency, four separate circuits operate simultaneously. Triggers multiple relays without signal overlap.
- Momentary Output Mode: Through momentary output logic, the TTL signal triggers only during button-press. Stops the action immediately upon button release.
- Wide Voltage Input: At a 5-12V DC operating range, the receiver unit stays powered. Matches standard battery packs or Arduino rails.
- Long Range Transmission: Under open field conditions, the 50-100 meter range persists. Penetrates standard brick walls in BD homes.
- ASK Modulation: Despite heavy electromagnetic interference, ASK modulation maintains signal integrity. Sensitivity remains at -98 dB for detection.
Frequently Asked Questions
What is the range of 433MHz RF remote?
The module reaches 50 to 100 meters in open spaces. Physical obstacles like concrete walls reduce this distance significantly.
How to connect 4 channel RF module to Arduino?
Wire the VCC and GND pins to the Arduino's 5V and Ground. Connect the D0-D3 output pins to digital input pins for signal processing.
