Product Description
The DFRobot Gravity: Digital Wireless Transmit Switch (433MHz) is an RF digital I/O module for wireless transmission of simple digital switching signals. The set includes one transmitter module and one receiver module and is based on 433 MHz RF communication. It is intended for applications where digital states need to be transferred over a short distance without complex protocol configuration.
The module is compatible with controllers that can read and write digital signals. With an operating voltage of 3.3 to 5.0 V DC, it can be integrated into typical microcontroller systems. According to the supplier data, the stable transmission distance is up to 15 m indoors. The interface is implemented in the Gravity ecosystem and provides a total of 4 interfaces.
