![]() ![]() 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.
