Product Description

The Wireless Transmitter Module operates at 433 MHz and uses ASK modulation to send digital data wirelessly over distances of up to 100 meters in open-air conditions. It features a simple single-pin digital interface, making it incredibly easy to integrate with popular microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi. With a wide operating voltage range of 3V to 12V DC, this module is versatile enough for battery-powered and bench-powered projects alike. Higher supply voltage results in greater transmission range and signal strength.

This transmitter module is commonly paired with a compatible 433 MHz wireless receiver module (sold separately) to create a complete one-way or multi-channel wireless communication link. It is widely used in home automation, remote control systems, weather stations, wireless sensor networks, and IoT prototyping.
