We used an ESP8266 based development board NodeMCU to collect temperature data from a low cost temperature sensor and is sent to a data analytic tool. The analysed data is displayed on the website along with the location on the website. This data can be used to provide suggestions to the user based on the weather. Such sensors can be implemented in different parts of the city to obtain more accurate results.
