Lumkani is a social enterprise based in South Africa that develops innovative early-warning IoT heat sensors aimed at mitigating the impact of fires in urban informal settlements, particularly in shacks. Founded in 2014, the company utilizes a heat detection technology that monitors temperature changes to detect fires. When a fire is detected, Lumkani's devices, which are networked to connect within a 60-meter radius, alert families in the vicinity, facilitating a swift community response. This technology not only reduces the risk of fire-related destruction but also aims to enhance safety and resilience in vulnerable urban areas.
