The acquisition of data refers to the continuous reading of the data of any of the sensors that we connect. Here we are connecting the temperature sensor (LM35). LM35 continuously reads the data and sends it to the RF transmitter via the microcontroller. The controller sends the data to the transmitter and the data is received by the receiver. This is an ongoing process.
The electromagnetic frequency ranges are above the audio range and below visible light. Any transmission of broadcasting, from the AM radio to the satellites, falls within this range. Radiofrequency (RF) itself has become synonymous with high frequency and wireless signals that describe anything from AM radio from 535 kHz to 1605 kHz to 2.4 GHz computer networks. However, Radio Frequency has traditionally defined The frequencies of about kHz to ~ 1 GHz with microwave being the consideration.
The RF transmitter module for this project is TLP434A (433.92MHz). This is an Ultra Small Wireless Transmitter ideal for remote control projects or data transfers. This compact unit operates between only 2V to 12V we are using 5V and a range of up to 200m is possible with an antenna equipped with 12V battery. This module can work directly with HT12D or a similar decoder. Here we are using the microcontroller as decoder.
The data generated by the microcontroller is displayed on the LCD on the transmitter side and transmitted through the RF transmitter (TLP434A). The RF transmitter will generate a carrier signal with a frequency of 433 MHz to transmit and the resulting signal will be transmitted through the antenna. The data transmitted by the antenna on the transmitter side are received by the antenna on the receiver side and the data obtained is given to the RF receiver (RLP434A) which is a compact radio (RF) receiver which works directly with the transmitter TLP434A At an operating frequency of 433.92 MHz. Data obtained from the RF receiver are received in series by the microcontroller. The data is decoded and displayed on the LCD on the receiver side.
