433MHz Transmitter Receiver Wireless Module

433MHz Transmitter Receiver Wireless Module The 433MHz Transmitter and Receiver Wireless Module Set is a simple and cost-effective RF communication solution designed for short to medium range wireless data transmission. Operating in the 433MHz ISM band, this module pair is widely used in remote control systems, wireless switches, sensor data transmission, and DIY electronics projects.The transmitter module sends digital data using ASK/OOK modulation, and the receiver module receives and demodulates the signal, providing a digital output to a microcontroller or logic circuit. These modules are easy to interface with Arduino, PIC, AVR, ESP, and other microcontrollers.Due to their low cost, simple design, and reliable performance, these 433MHz RF modules are extremely popular in home automation and wireless control projects.Click here to view related productsFeaturesOperating Frequency: 433MHz ISM bandIncludes: 1 × Transmitter module 1 × Receiver moduleModulation: ASK / OOKLow power consumptionSimple digital data interfaceCompatible with HT12E/HT12D, PT2262/PT2272, or microcontrollersGood range for hobby and DIY projects (typically 50–200m with proper antenna)Compact and lightweight modulesLow cost and easy to useExternal antenna support for better rangeApplicationsWireless remote control systemsHome automation and wireless switchesWireless doorbells and alarmsSensor data transmissionRobotics and RC projectsGarage door and gate controllersWireless relay controlDIY electronics and IoT projects*Product image for illustration purposes only, actual product may vary.
