The Digital Computerized Measurement System for Chemistry is a modern educational platform that integrates hardware, software, and multimedia content with advanced artificial intelligence to foster engaging and inclusive learning. Each wireless sensor features a 1.8-inch color LCD for real-time data display and operates autonomously without the need for external data loggers, analog-to-digital converters, or cables to connect to computers or tablets.
The system includes a wide array of specialized sensors: – Temperature (-50°C to +200°C; 0.01°C resolution)
– Pressure (0–700 kPa; 0.1 kPa resolution)
– pH (0–14 pH; 0.01 resolution)
– Carbon Dioxide (0–50,000 ppm; 1 ppm resolution)
– Electrical Conductivity (0–20,000 μS/cm; 1 μS/cm resolution)
– Oxygen (0–100%; 0.1% resolution)
– Colorimetric (0–100%; 0.01% resolution)
– Salinity (0–100 ppt; 0.1 ppt resolution)
– Drop Counter (0–240 drops/min; 1 drop/min resolution)
– Ion-selective sensors for quantitative analysis of carbonate, nitrate/nitrite, sulfate, fluoride, and chloride concentrations in aqueous solutions.Complementing the hardware, the LMS-hosted digital curriculum provides inquiry-based modules for chemistry, biology, physics, and STEM. These materials include experiment scenarios, step-by-step instructions, video demonstrations, and interactive exercises, all specifically calibrated for use with the provided equipment.
An integrated RAG-based AI Agent further enhances the lab experience by assisting with research task selection, explaining experimental procedures, and providing personalized feedback based on student proficiency. The agent helps prepare research reports and offers recommendations based on common mistakes, all while operating within a localized knowledge base aligned with national educational standards.
