IoT based weather station
A weather station can be described as an instrument or device, which provides us with the information of the weather in our neighbouring 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, light intensity, 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 above mentioned 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 ESP8266 based Wi fi module Nodemcu (12E) Four sensors are connected to the NodeMCU namely temperature and humidity sensor(DHT11) pressure sensor(BMP180) raindrop module, and light dependent resistor(LDR) Whenever these values exceed a chosen threshold limit for each an SMS, an E mail and a Tweet post is published alerting the owner of the appliance to take necessary measures.
