I am working in a biopharmaceutical manufacturing facility and want to automate part of our UF/DF (Ultrafiltration/Diafiltration) process to reduce manual control of the Watson-Marlow 520 peristaltic pump. Currently, the process requires operators to manually adjust pump speed to maintain Transmembrane Pressure (TMP) within limits (typically ±0.3 bar). I want to build a real-time monitoring and control dashboard using Node-RED or similar open-source platforms that can: • Read pressure, pH, and conductivity values from sensors via Arduino or Modbus. • Calculate TMP in real time. • Implement a PID control loop to automatically regulate pump speed via RS-485 (Modbus RTU). • Display live data on a simple web dashboard (Node-RED UI) with graphs and alarms. &bull...

The Ultrafiltration/Diafiltration (UF/DF) process is a critical step in downstream biopharmaceutical purification, used to concentrate and buffer-exchange monoclonal antibodies prior to formulation. Traditionally, the operation is manually controlled — operators adjust the Watson-Marlow peristaltic pump speed to maintain the transmembrane pressure (TMP) within the target range. This manual regulation leads to frequent TMP fluctuations (±0.3 bar), inconsistent flow rates, and significant operator workload. Such variability can impact product recovery, increase process cycle time, and pose challenges in achieving consistent performance across batches. This project aims to optimize and simplify the UF/DF process by implementing a low-cost automation and monitoring system using N...

I am building a home DWC hydroponics system based on a detailed technical plan (Phase 1). I have the GitHub repository for the software setup but need expert help with the physical hardware integration, as I have no wiring experience.

The componentmust be designed to act as an integration bridge, ensuring a robust and mapped data flow between The Things Network (TTN) and Autodesk Tandem: The Things Network (TTN) Connectivity A dedicated module for authenticating and subscribing to TTN's MQTT service or its integration API (Webhook) to receive real-time LoRaWAN message payloads. Payload Decoding and Parsing Capability to process the raw data format (payload in bytes) sent by LoRaWAN devices and decode it into readable and usable values (e.g., temperature in Celsius, ON/OFF status). Data Mapping TTN to Tandem Asset A configuration tool (UI) that enables the unique mapping of a specific sensor (identified by its TTN Device ID) to a specific property of an Asset registered in the Tandem Digital Twin (identified ...

Project Title: ICT for Intelligent Transportation Systems (ITS) Project Description: Our project aims to apply Information and Communication Technology (ICT), Artificial Intelligence (AI), and the Internet of Things (IoT) to improve the quality and safety of transportation in cities. The main goal is to reduce traffic congestion and air pollution, which are two of the most critical challenges in urban areas today. The system we designed works by sensing, communicating, analyzing, and controlling traffic conditions in real time. It uses a network of sensors installed on the roads to monitor vehicle density, pollution levels, and emergency situations. These sensors continuously send data to a central control unit. Using AI and machine learning algorithms, the system analyzes the data and...

I need a patient, fluent-in-Telugu tutor who can guide learners through Full stack development, Cybersecurity, and the Internet of Things,Blockchain,Data science starting from the absolute basics and moving all the way to advanced, job-ready skills. All sessions will be delivered online, so a stable setup for screen-sharing, live coding, and interactive white-boarding is essential. Who you’ll teach • A mixed cohort of beginners, intermediates, and a few advanced learners eager to sharpen specific skills. • Classes will be scheduled in small groups; one-to-one doubt-clearing slots may follow each module. What I expect you to provide • A structured syllabus for each track (foundation, intermediate, advanced). • Live, hands-on demonstrations—think bui...
