IoT based Weather station using Ndoe MCU
Call for Price
In this IoT Project weather station was implemented using Node MCU
Building a IoT based monitoring system involves periodically update the data in the cloud and avoids the data losses due to improper monitoring of sensors. By using IoT based weather station , we can monitor and get the data values at anywhere and anytime. For this we are using NodeMcu ESP8266 module. By using ESP8266 , we can upload the data’s to the Thingspeak cloud. We can get the temperature and humidity levels of the atmosphere by using LM35 , and DHT11 sensor . We can read the data from these sensor and analyze it graphically from anywhere in the world.
The existing weather monitoring system generally use weather stations , which uses multiple instruments such as barometers, thermometers, rain gauge etc. These devices are using analog technology which is later physically recorded and stored in a database . After, this information will sent to the radio and news reporting stations.
In this project ,we have developed IoT based weather monitoring system which involves monitoring the temperature , humidity in the environment. For this we are using NodeMcu ESP8266 as the main controller. To monitor the temperature and humidity,we are using LM35 and dht11. We can get these sensor values continuously and upload the data’s to the Thingspeak cloud. We can access these data values at anywhere in the world using network connection.
