PT2272 315MHz 4-Channel Remote and Receiver Kit

The PT2272 315MHz 4-Channel Remote and Receiver Kit with fixed code is one of the most widely used modules for wireless control of electric devices. This 4-Channel Remote and Receiver allows users to control various appliances remotely without requiring advanced technical knowledge. Operating at 315MHz, it uses ASK (Amplitude Shift Keying) modulation for stable, noise-free signal transmission.

The receiver operates at 5V DC with a standby current of 4.5mA. Its compact design, measuring 41×23×7 mm, allows easy installation in various projects. The built-in PT2272 315MHz Remote and Receiver chip uses a fixed code system, ensuring secure and reliable signal reception.

This PT2272 315MHz Remote and Receiver features four buttons on the remote, each corresponding to pins D0, D1, D2, and D3 on the receiver. Pressing a button sends the matching signal, while the VT pin indicates output status and can be used to control relays. The transmitter operates at 12V DC with 10mW output power, providing a signal range of 50–100 meters in open space. This 4-Channel Remote and Receiver is ideal for applications such as electric gates, roller shutters, automatic garage doors, relay and light control systems, as well as smart home and security projects.

The kit includes a Wood-Style Remote and a receiver board with decoding capability, enabling direct connection to relays and appliances. It is suitable for electronic projects, practical training, motor and sliding door control, alarm and security systems. Quick and easy setup without extra tools, along with compatibility with industrial and home projects, makes this system highly versatile. With the PT2272 315MHz 4-Channel Remote and Receiver Kit, users can build secure, stable wireless systems with a reliable and user-friendly experience.

Additionally, this system supports smart home projects, remote control of lighting, relays, and small motors. Its compact design and low power consumption make it an ideal choice for both home and industrial applications. Combining the four-channel capability, PT2272 chip, and 315MHz frequency ensures precise, multi-channel wireless control, allowing users to implement synchronized systems effortlessly.
