Make no mistake sensors will drive the next-generation user experiences. We’ve just got started with wearables.

The Internet of Things (IoT) is a term that refers to the network of devices that connect to each other via the internet. It involves connecting commonplace items or things to the internet via sensors and IP addresses. Anything from your shoes to your automobile to your coffee pot may be considered an everyday object. Connecting these gadgets to the internet allows data and user analytics to be extracted. The data and analytics gathered may be utilised for a variety of purposes, including surveys, automation, alerts, and just improving user experiences.
This project is primarily a hardware device with a hint of IoT. We have two systems: a frontend system, which will be our hardware device, and a backend system which will be our server. Our IoT setup will constitute an in-house JKUAT SES development board which is based on the ESP32 WROOM chips(i.e Any ESP32 chip can therefore be used as an alternative) and a DHT11 module as our temperature and humidity sensor. With this, we can send temperature and humidity data to our backend services for monitoring purposes.
For connectivity, the ESP32 chip has an in-built WIFI module that allows us to go into production by deploying the device to homes given that most homes have WIFI installed.
