Abstract

The environmental monitoring or detecting device which is a data logger can be used to extract information on the temperature and the humidity of certain vicinity or area which is a very paramount criteria or yard stick to ascertain the atmospheric condition of a particular geographic location in real time anywhere globally. This distinctive device is made up of different hardware accessories interfaced appropriately together to achieve the best result in terms of accuracy and precision. Since this unique device is utilized for precise and accurate temperature and humidity readings, the electronic components used (active and passive) were meticulously selected for optimal performance. A programmable Micro controller board and a Micro controller unit is needed to work in synergy with other peripherals to achieve desirable results. We utilized the Arduino microcontroller board or its clones as it is the proposed and recommended microcontroller suitable for optimal performance of the data logging system. We also incorporated the ATMEGA328p (dual in line package version) as our micro controller unit/chip. This display unit consists of a 20*4 (80 digits) 7 segment LCD display module (Hitachi HD 44780) compatibles or drivers and an OLED Display connection. The objectives of interfacing a dual display system are to extend the visualization of data display in real time to our extended environmental monitoring section. High accuracy and precision temperature and humidity sensor unit is interfaced in this unique work to achieve very precise and accurate readings. This sensor (SHT21) is also a low power digital temperature and humidity sensor. We now finally interface a versatile low cost and a high integrated Wi-Fi micro controller chip that enables our micro controller to communicate via Wi-Fi connection and execute basic TCP/IP transmissions. The whole hardware circuitry mode of operation is determined by the software programmable codes (source codes) written to the hardware circuit connection/interface via a USB connection to a computer system or device
