The system aims to design a reliable embedded system that will be used in measuring various atmospheric parameters for up-to-date weather monitoring. Weather is monitored with the help of payload equipment which acts as a transmitter in which temperature, pressure, humidity, altitude, air quality, and light detection is measured with the combined action of all the sensors. These measured values are then transmitted to the ground receiver to view the information from the various sensors. NRF frequency signals are used for the communication between transmitter and receiver respectively. All the sensors and the transmitter/receiver module would be connected to the main Arduino/Microcontroller. The data received would be continuous and can be viewed from time to time on the receiver module, smartphones, and cloud storage simultaneously. The project is developed to produce a weather monitoring device capable to measure with more accuracy, reliability, and cost-efficiency.
