Weather station for homes and offices using thingspeak application / Halim Rozman

The Internet of Things (IoTs) has greatly diminished power usage, enhanced connectivity, and streamlined data access for networked devices. It is commonly acknowledged as a dependable technique for increasing diverse industrial sectors. The primary objective of the article is the utilisation of IoT in the development of a weather monitoring system. The system utilises many sensors that are integrated with an Arduino Uno microcontroller board. The study seeks to collect, assess, and analyse the execution and depiction of data. The Arduino Uno functions as the primary server, facilitating internet connectivity to retrieve data for analysis and scrutiny. A weather station is an apparatus that offers precise information regarding the current weather conditions in a specific area, encompassing factors such as temperature, air pressure, and gas detection. The prototype relies on the ESP8266-based Wi-Fi module Nodemcu (12E) as its central component. The NodeMCU is connected to four sensors: the DHT11 temperature and humidity sensor, the BMP180 pressure sensor, and the MQ-135 air quality sensor. The hardware configuration incorporates an LCD 20X2 display for the purpose of displaying the sensor readings. Whenever the measured values surpass predetermined criteria, the system dispatches notifications via a web-based application to prompt users to undertake requisite actions.
