315MHz RF Transmitter Receiver Wireless Module

The 315MHz RF Transmitter and Receiver Module Pair is the go-to solution for anyone looking to add wireless capabilities to their projects without breaking the bank. This low-cost yet highly effective wireless data communication kit is perfect for a vast array of applications, from building simple remote controls and wireless sensor networks to creating sophisticated home automation systems. The modules operate on the globally recognized 315MHz frequency band, making them a popular and accessible choice for hobbyists and professionals alike.

The modules employ Amplitude Shift Keying (ASK) modulation, a simple method that makes them easy to interface with microcontrollers like Arduino and Raspberry Pi. The transmitter module typically operates on a wide voltage range (3V to 12V), while the receiver is a 5V module with low power consumption. This design flexibility allows for use in both battery-powered and mains-powered projects. With an effective range of up to 100 meters in open space and data rates up to 10kbps, they are more than capable of handling simple data transmission for projects such as wireless doorbells, garage door openers, and remote-controlled lighting.

The transmitter module sends digital signals wirelessly via its antenna pin, while the receiver module detects and outputs the transmitted data. Paired with a simple encoder/decoder (like HT12E/HT12D) or software serial, it allows basic one-way wireless communication between devices.
