Specification

Description

Wireless Alarm Using RF Module is designed as a security system that can be controlled wirelessly using the RF module. In the kit Wireless Alarm Using RF Module HT12E encoder IC takes a 4-bit binary sequence from the DIP switch. Each binary sequence notifies the identity of the item. Since we have used a 4-bit channel, we can allocate 16 items (in our case four). The encoder converts this four-bit binary sequence into serial data with address data latched with it.

The signal generated from the encoder is not strong enough to be transmitted for quiet fine ranges of distance so this needs to be modulated and transmitted over a carrier. We have used an RF Transmitter working on 433 MHz, 4800bps baud-rate, and uses ASK modulation technique to serve this purpose. Thus, the data lines of the IC are used to differentiate between different ids and these are transmitted over the RF channel.

The next section is the RF receiver. There is an 8 terminal RF receiver that has the same properties as configured for the RF transmitter. It receives the serial data wirelessly depending upon the RF communication protocol. The receiver sends the serial data to the HT12D IC, which converts this serial data in parallel data of 4-bit, the same as enabled on the transmitter end. It indicates Alarm As Output.
