Aurel 650201139G is a solar/battery powered radio frequency (RF) remote control, also known as a wireless remote. It is made up of a receiver and a hand-held transmitter, which sends a signal to the receiver when a user presses one of its buttons. The receiver is usually mounted on a wall and is connected to a device, such as a motor or a lighting system, which then responds to the transmitted command. The RF remote control operates in the 433.92 MHz frequency and has a transmission range of up to 150 meters in open air. It requires two AAA batteries to power it, but it also comes with a 5V solar panel, which allows the remote to be recharged by the sun.
