Tech Intro

Transmitters use the unique PUSH-RF technology which is the energy harvesting wireless technology and ultra low power technology. When the button is pressed, it will trigger the micro-generator, the direction of the magnetic circuit in the micro-generator would change. The rapid magnetic flux change leads to an induced voltage, in other words, mechanical energy is changed into electric energy.

RF-transceiver of the receivers receive the wireless signals, microcontroller identifies the signals. If the signals are right and the pairing between receiver and transmitter is successful, the music chip in the receivers will be triggered; then the loudspeaker plays beautiful music to tell the host there’s a visitor waiting at the door.
