Nithin-Kannan/Kerala-IOT-Challenge

Kerala IOT Challenge

Foxlab Makerspace in association with GTech - Group of Technology Companies in Kerala is launching our prestigious program “Kerala IoT Challenge 2021”, with a vision to mould 100 IoT experts in Kerala, hosting on the µLearn platform. Kerala IoT Challenge is a program designed in 4 levels followed by a hackathon to identify and train quality industry leaders in the IoT domain, while any novice learner can start with layer 1 and others can enter laterally to the desired layer after an evaluation.
