In order to draw the attention of the recipient computer for the message received from the sender computer, an audio beeping system is interfaced from the MAX232 Transmitter pin duly inverted two times by a pair of transistors Q1 and Q2 (BC547) to a 555 monostable multi-vibrator through its triggering pin2. The modules are powered by onboard regulated 3.3V power supply meeting the voltage requirement of the device by 3.3V regulator being fed after getting the 5V from the regulator. The interfacing from the XBee modules is done through level shifter IC MAX232 as shown in the figure. How XBee Module Works:įrom the below circuit, we used two trans-receiver 2.4GHz XBee modules for two computers. The modules are ideal for battery-powered applications. Automatic collision avoidance is additionally given with clear channel evaluation features. Extensive hardware support is provided for packet handling, information buffering, burst transmissions, and link quality implication. The transceiver module furnishes a complete RF subsystem that can be utilized to transmit and receive data at up to 500Kbps from any standard CMOS/TTL source.

It can be used as a serial replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The module can communicate up to 100 feet indoors or 300 feet outdoors. The XBee is an arrangement of modular products that make deploying wireless technology easy and cost-effective. Wireless technology can be challenging without the right combination of expertise and resources.

Zigbee standards are standards with a range between Bluetooth and WIFI. XBee modules are wireless communication modules that are built based on the Zigbee standard. RF Transmitter Circuit: RF Transmitter Circuit RF Receiver Circuit: RF Receiver Circuit It has many applications in various areas like Remote lighting controls, long-range RFID, wireless alarm and security systems, etc. Video on 433 MHz RF Transmitter and Receiver: When logic 1 is applied to transmitter then the transmitter is ON and there is a high power supply in the range of 4.5mA with 3V voltage supply. When logic 0 applied to transmitter then there is no power supply in the transmitter. RF transmitter receives serial data and transmits to the receiver through an antenna which is connected to the 4 th pin of the transmitter. It operates at a specific frequency of 433MHz.
RF signals travel in the transmitter and receiver even when there is an obstruction. In many projects, we use RF modules to transmitting and receive the data because it has a high volume of applications than IR. Also by using this device at higher transmitted power will create interference with other RF devices. However, which will result in a high electrical power drain on the transmitter device, which causes a shorter operating life of the battery-powered devices. Main Factors Affecting RF Module’s Performance :Īs compared to the other radio-frequency devices, the performance of an RF module will depend on several factors like by increasing the transmitter’s power a large communication distance will be gathered. Transmitter and the receiver are duly interfaced to two microcontrollers for data transfer. The data is sent serially from the transmitter which is received by the tuned receiver.
When logic one is sent carrier is fully on to about 4.5mA with a 3volts power supply. The transmitter draws no power when transmitting logic zero while fully suppressing the carrier frequency thus consume significantly low power in battery operation. Basically the RF modules are 433 MHz RF transmitter and receiver modules.
