![]() ![]() Receive the data from the RF receiver module.An Arduino NANO board as a microcontroller to perform these tasks:.An ASK based RF receiver module with a 433MHz carrier frequency to de-modulate and receive the data transmitted by the sensor node of the RF TX module.The receiver consists of an RF receiver module, an LCD panel, indicating LEDs, potentiometers, and a microcontroller. One LED that blinks to indicate the sensor node is active and is properly transmitting data.A 9V battery is to provide power supply to the transmitter node.An ASK based RF transmitter module with 433 MHz carrier frequency to modulate and transmit the data to the receiver.An Arduino nano board as a microcontroller that reads the temperature from the LM35 in analog voltage and provides this data to the RF transmitter.A temperature sensor (LM35) to sense the surrounding temperature and provide analog output voltage, corresponding to the actual temperature.The transmitter consists of four items: the temperature sensor, a microcontroller, an RF transmitter, and a battery. ![]() The complete system is divided into two distinct blocks:
