Broadly speaking, the Internet of Things (IoT) describes a world in which physical objects are capable of autonomously transferring data about themselves and their environment to other devices. At the heart of this diverse and scattered ecosystem are sensor nodes whose job is to collect information via environmental, physical, or relational sensors then process and transmit that information to the users or the cloud for further processing and analysis. That data can be used to trigger actions, to track changes or pass on useful information to make users’ lives better and more convenient or enable machine to be more efficient.
The drive to develop a new generation of sensor devices that are always on and always aware will increasingly push the boundaries of ultra-low power. By dramatically reducing overall system power, these systems will be able to last much longer on their batteries or use smaller batteries to reduce size, and also require little to no maintenance to make them more user friendly and ubiquitous.
Ambiq Micro’s ultra-low power Apollo family microcontrollers with SPOT technology are key enablers for this new generation of sensors by enabling them always on and always aware with its industry leading energy efficiency and integrated ARM Cortex M4F processor.
