    InterconnectA

    This project aims to design and develop a modular monitoring system for a LiC supercapacitor array, incorporating PCBs A and B for voltage sensing on either side of the array, and PCB C for central control. PCBs A and B will measure cell voltages, communicate data via I2C, and feature activity/status LEDs, powered directly from the array. PCB C will aggregate data, managing over/under voltage, overcurrent, and balancing. The goal is a compact, efficient solution to ensure the array's safety and longevity.

    ESP32-WROOM-32E Reference Design

    This project involves designing a versatile IoT sensor hub using the ESP32-WROOM-32E module. The main objective is to create a platform that enables seamless data collection and transmission from various environmental sensors over a WiFi network. The device will feature USB-C for power and data transfer, and will utilize on-board voltage regulation to ensure stable operation. A CH340C chip is employed for USB to serial conversion, facilitating easy programming and communication with a host computer. Key Features: Wireless Connectivity: Leverage the ESP32's built-in WiFi capabilities for real-time data transmission to cloud-based platforms or local servers. USB-C Interface: Utilize a modern USB-C connector for power and data transfer, providing flexibility and future-proofing the design. On-board Voltage Regulation: Include an AMS1117-3.3 voltage regulator to maintain a stable 3.3V output from the USB input, protecting sensitive components. Support for Multiple Sensors: Integrate various GPIOs to connect multiple sensor types ( temperature, humidity, air quality ) (temperature, humidity, air quality) for comprehensive environmental monitoring. Expandability: Design with additional headers for future expansion, enabling users to customize and extend the hub's capabilities with additional sensors or modules. Applications: Smart Home Automation: Integrating with home systems to monitor and respond to environmental changes. Environmental Monitoring: Providing data for ecological studies or urban environment monitoring. Industrial IoT: Enhancing systems within a factory or industrial setting to track conditions in real-time. With this setup, the device aims to be a robust and adaptable piece of technology, suitable for hobbyists, researchers, and developers interested in the expanding world of IoT.

    To optimize your 4-layer board manufacturing process with Seeed Studio Fusion, utilize this comprehensive template. It incorporates a majority of the essential manufacturing constraints as global rules, ensuring a smoother and more efficient production workflow. #project-template #template #manufacturer-design-rules This project is a vessel monitoring system built using Seeed Studio Xiao Sense, Xiao Expansion Board with OLED, a UART WiFi module, a normally open float switch, and a UART SIM800L cellular module. The system displays a 30-second countdown on the OLED screen, calibrates the IMU sensor, converts to Euler angles, and stores these values for comparison with future readings. It also sets up the WiFi module as an access point to configure the vessel's name, contact numbers, and angle thresholds for list and trim notifications. Reports are sent at specified times via the cellular module.
