A Bluetooth® low energy system-in-package (SIP) that supports ultra-low power connectivity for data communication. Built into every ASR-1 is a security chip, preprogrammed to operate in conjunction with the Afero Cloud, as well as the Bluetooth radio, and a dedicated Hardware Security Module (HSM). The dedicated HSM brings added layers of security and authentication to every device. ASR-1 is especially suited for small form factor devices and low-power applications, well designed for the Internet of Things.
