The weather in Nigeria is awful. Temperatures rise above 37 degrees celsius, which causes some edible foods to spoil. Let's say you buy a product and it says don't allow the temperature rise above a certain value. How do you measure and monitor the temperature? Look no further, there are sensors in the market today but for the focus of this tutorial, we'll use DHT11 temperature and humidity sensor. We can read the values using an Arduino microcontroller and after visualize the data on an LCD. This tutorial http://blog.nerdshed.com.ng/2017/05/12/build-a-temperature-and-humidity-station/ will guide you in setting up your own station.
