RF 433MHz Tx_Rx Module

The 433MHz RF Tx/Rx Module is a cost-effective wireless communication solution widely used in hobbyist and industrial applications. This pair operates at 433.92MHz (and optionally 315MHz) using ASK (Amplitude Shift Keying) modulation, allowing for simple wireless data transmission over short to medium distances. The transmitter operates at 3-6V with low power consumption, while the receiver offers high sensitivity (-105dB) for reliable signal reception. It supports an external antenna (typically a 32cm spiral wire) to enhance range up to 100 meters in open space. Common applications include remote control systems, home automation, wireless sensor networks, and robotics. This module is compatible with popular microcontrollers like Arduino, making it a favorite for DIY projects. Choose this module for its ease of use, low cost, and proven reliability in various wireless applications.
