Microbit and WiFI

Hello. I have been using Microbits in education for a long time. I want to move into using WiFi with them to send data to the Cloud in real time (i.e. temperature data). What would you recommend for the best way/modules to do this along with a simple web platform (i.e. ThingSpeak)? I prefer ease of use in a classroom setting over power and complexity. thank you, Steve
