This research paper presents a design of a low-cost data logger system specifically developed for monitoring systems that require large-scale data storage that enables wider accessibility, versatility, and deployment in various applications. The proposed system employs an Arduino Mega 2560 board in conjunction with an ATmega2560 chip to facilitate data logging operations. DHT22 sensor is used to monitor temperature and humidity. The Arduino mega 2560 collects the raw data from a sensor then the data is transmitted by controller to a node MCU for data acquisition and subsequently stores the acquired data onto the SD card in .CSV format . The obtained results and findings are precisely compared against data collected using a calibrated thermometer and psychrometer during the rigorous testing phase. This comparative analysis is used to evaluate the accuracy and reliability of the system. The obtained results are subjected to comprehensive scrutiny to determine the system's accuracy, precision, and consistency. The accuracy obtained for temperature measurement is +/-1.25% of full scale deflection.
