IoT Based Weather Monitoring and Intimation

Abstract

A weather station can be described as an instrument or device, which provides us with the information of the weather in our neighboring environment. For example it can provide us with details about the surrounding temperature, barometric pressure, humidity, etc. Hence, this device basically senses the temperature, pressure, humidity, rain value. There are various types of sensors present in the prototype, using which all the aforementioned parameters can be measured. It can be used to monitor the temperature or humidity of a particular room/place. With the help of temperature and humidity we can calculate other data parameters, such as the dew point. In addition to the abovementioned functionalities, we can monitor the light intensity of the place as well. We have also enabled to monitor the atmospheric pressure of the room. We can also monitor the rain value. The brain of the prototype is the SIM900aGSMmodule. Four sensors connected to the Arduino are temperature sensor (ds18b20)and humidity sensor (DHT22), pressure sensor (BMP180), raindrop module. These sensors are sending the data to Arduino module. Then Arduino module sends these data to the IoT server with the help of GSM module. We can monitor the data continuously in IoT server. Whenever these sensors parameter exceed a chosen threshold limit, an SMS is published alerting the user of the appliance to take necessary action. Each sensor has its own threshold point.
