Glory Wireless Doorbell Schematic Circuit Diagram

This is a circuit of a wireless rf remote control doorbell using low cost and commonly available components.

Wireless doorbell schematic circuit diagram. This is an easy to make electronic doorbell circuit. This project is a wireless doorbell so we can get rid of the hustle on the wiring job. An excellent transistor is critical in the rf phase and the japanese transistors are undoubtedly suits this objective.

The wireless doorbell transmitter and receiver circuit are incorporated below. The battery can be replaced with a large flashlight type dry cell rated at 12 to 16 volts and if the wires are still intact and the contacts. The battery is the weakest link here and should be the first place to look for trouble.

This project uses rf radio frequency for the transmitter and the receiver circuits to communicate. Add a doorbell chime to your shop or garage by connecting to either the connect the new chime to the existing chime by matching the wire connections. As illustrated in the above diagram the parts of an old doorbell circuit include.

The transistor employed in the. The transmitter circuit is made up of 303mhz rf oscillator and 32khz crystal controlled oscillator. The most fundamental constituent is the transistor.

All transistors are 2n3563 the u shape coil is a single half turn using a 1mm copper wire with 5mm diameter. Wireless doorbell the transmitter circuit is made up of two building blocks the 303mhz rf oscillator and the 32khz crystal controlled oscillator. The working range is upto 20 meters.

The 303mhz oscillator consists of a self oscillating circuit made up of the coil. The circuit of the wireless bell shown here is easy to built and using only few easy to find low cost components. I would like to install a 2nd wired westminster chime doorbell that that do not fit my needs and diagrams for a single bell dual button set up.
