Industrial Smart Hardware Design

This project aims to design a robust and reliable IoT connected temperature probe for commercial composting applications. We have a working prototype using Arduino but need a detailed CAD design for manufacturing, as well as PCB and software design.

Project Requirements:

1. Probe Specifications:

Material: Stainless steel tube
Length: 1 meter
Diameter: 15mm
End: Sharp point housing the thermometer probe
Handle: Horizontal handle below the control box, made of the same stainless steel tube, 40cm wide (20cm extension on each side)
2. Control Box Specifications:

Material: Plastic
Dimensions: 20cm wide, 15cm long, and 15cm high
Components:
PCB: With IoT capabilities
Battery: Lithium Ion, 10-15cm long, 8-10cm wide, 4-5cm high, mounted under the PCB
Solar Panel: Approximately 18cm x 13cm, set into the lid
USB-C Charging Port: External, with a rubber plug for weatherproofing
LED Indicator: RGB LED to indicate device status
On/Off Selector Switch
3. Connections and Sealing:

Threaded Female Section: At the bottom of the control box for receiving the probe's threaded male connection
Wiring: Connection from the thermometer at the end of the probe to the control box through the body of the probe
Sealing: Rubber seals/gaskets at all connection points to prevent water ingress
4. Environmental Considerations:

The control box and all components must be weather-resistant to withstand outdoor composting conditions.
5. PCB and Software Design:

PCB Design:

Design and layout of the PCB to fit within the specified dimensions of the control box
Integration of components including the microcontroller, battery management system, and connectivity modules (e.g., WiFi, Bluetooth)
Design for power efficiency to ensure optimal performance with the solar panel and battery
Software Design:

Development of firmware for the microcontroller to manage temperature data collection, connectivity, and power management
Implementation of IoT capabilities to allow remote monitoring and data logging
Development of a basic user interface for data access and device control (e.g., mobile app or web interface)
Project Scope:

Detailed CAD design of the temperature probe and control box
PCB design and layout
Software and firmware development
Consideration of manufacturing feasibility and durability
Design files suitable for prototype manufacturing
Required Skills:

Proficiency in CAD software (SolidWorks, AutoCAD, Fusion 360, etc.)
Experience with IoT device design and integration
PCB design and layout experience
Software and firmware development for microcontrollers
Knowledge of materials, especially stainless steel and plastics for electronics housings
Familiarity with environmental and outdoor equipment design
Understanding of manufacturing processes, including prototyping and mass production
Deliverables:

Complete CAD design files for the temperature probe and control box
Technical documentation detailing component specifications, assembly instructions, and any special manufacturing considerations
PCB design files and schematics
Firmware and software code with documentation
A working prototype for testing and validation
