Customer Location: Florida, USA

Requirements: A customer wants to design a battery-driven board that can measure pulses from the energy sensors and provides calculated pulses to the server on a regular basis according to configured time. The device’s battery needs to last for a minimum of 10 years with precise pulse counting.​

Solution: We’ve provided support for Hardware designing, Firmware development, server management, and the project’s web portal. We designed STM32L based hardware with power-controlled peripherals to protect battery life. Firmware was developed with accurate pulse counting with battery efficient mechanism. Firmware was written in a flexible manner which supported different LTE modems with production configurations. FOTA supports STM32L and LTE modem with a selected audience.

We’ve helped with advanced technology and excellent customer support and services to achieve the client’s goals.
