Accelerating IoT Product Development

Developing products that connect to the ‘Internet of Things' (IoT) isn’t easy; every new product or application requires a lot of different elements to work seamlessly together.

At ControlBits we provide hardware development tools, open-source software and infrastructure that already work together - dramatically reducing the risk and time-to-market of IoT products.


EMIT (Environmental Monitoring IoT) is an IoT hardware development board for the popular ESP32 IoT module. Designed to accelerate the development of solutions for the Smart Buildings, Environmental Monitoring and Smart Agriculture sectors, EMIT contains everything you need to quickly develop IoT based monitoring and control products and applications.
