MILIEU SENSORING DEVICE

摘要

A milieu sensoring device is composed of power system, sensors and control system used to monitor environmental condition such as carbon monoxide, relative humidity, temperature, dew point and light intensity which display the value on a computer. The control system uses Atmega 328 microcontroller unit as a brain of the whole device and used for controlling the whole operation of the device using a program arduino IDE that consists of digital temperature and humidity sensor DHT 11, light dependent resistor NORP-12, and gas sensor MQ-5 used to monitor different environmental parameters. The process of collecting the data comprises of (a) sensing, (b) analyzing the data by the MCU, (c) transferring the collected data from MCU to the computer, and (d) recording and displaying the data.
