The biological monitoring system PCB is an intelligent "ecological sensing hub" for tracking biological indicators in the environment. Designed for aquatic, terrestrial, and atmospheric biological detection, it integrates bio-sensor interfaces, data acquisition modules, and analysis circuits. With our PCBA team’s experience in low-power design, it supports long-term field deployment, detecting microorganisms, algae, pollen, and biodiversity-related data. It transmits biological information to ecological monitoring platforms, suitable for lakes, forests, wetlands, and urban ecosystems, aiding in ecological assessment and conservation.
