Water Quality Monitoring Solution Leveraging MYIR's MYC-YA157C-V3 SOM

In response to the need for efficient and long-term stable measurement in the water quality monitoring industry, a water quality monitoring system is required. This system should have online automatic analyzers as its core, utilizing modern sensing technology, automatic measurement technology, automatic control technology, computer application technology, and related specialized analysis software and communication networks to form a comprehensive online automatic monitoring system. It can detect abnormal changes in water quality early, make rapid warnings to prevent downstream water pollution, and achieve a combination of automatic observation, remote control, and wireless transmission. It can track pollution sources in a timely manner, thereby serving management decisions.

The MYC-YA157C-V3 System-On-Module (SoM) from MYIR, featuring the STM32MP157 processor from the STM32MP1 series, offers an excellent solution for Water Quality Monitoring. It includes dual Cortex-A7 cores running at 650 MHz, a Cortex-M4 core at 209 MHz, a 3D graphics processing unit (GPU) and an LCD-TFT display controller. This provides customers with a cost-effective development solution, equipped with rich interface resources to facilitate application expansion.
