Product Description
The DFRobot Gravity: Digital Wireless Receive Switch (433MHz) TEL0142 is an RF digital I/O module set for simple wireless transmission of digital signals in the 433 MHz band. The set includes one transmitter module and one receiver module and is intended for applications where switching signals must be transferred wirelessly without complex protocol configuration.
The modules operate from a 3.3 to 5.0 V DC supply and are compatible with controllers capable of reading and writing digital signals. According to the manufacturer, the stable transmission distance is up to 15 m indoors. The transmitter features very low standby current below 10 uA at 5 V, while the receiver is specified with defined standby and active current values for continuous operation.
