Industrial IoT Electricity Monitor PCB Design
Budget: $30 – $250 USD
Title: PCB Design for Low-Cost Industrial Electricity Monitoring IoT Device
We are looking for an experienced PCB design / embedded hardware engineer to design a low-cost industrial electricity consumption monitoring device.
The device will be used in an industrial factory environment to monitor electrical parameters and send data to a server through IoT.
Project Goal
We want to develop a compact and reliable PCB for monitoring:
Voltage
Current
Power consumption
Energy consumption / kWh
Power factor, if possible
Basic electrical health/status data
The device may use ESP32 or any suitable low-cost microcontroller, but the final solution must be practical, reliable, and cost-optimized.
Main Requirement
The most important requirement is low total product cost.
The PCB design must be optimized so that:
PCB manufacturing cost stays low
Component cost stays low
Assembly cost stays low
The product can be produced in bulk later
Components should be easily available from suppliers like LCSC / JLCPCB / China-based sources
The design should avoid unnecessary expensive components
Application Environment
This device will be used in an industrial electrical environment, so the design should consider:
Electrical safety
Noise and EMI protection
Stable power supply design
Isolation where necessary
Long-term reliability
Easy installation and maintenance
Protection against voltage fluctuation, surge, and industrial noise
Expected Work
The freelancer should be able to provide:
1. Hardware architecture suggestion
2. Component selection with low-cost alternatives
3. Schematic design
4. PCB layout
5. BOM with cost estimate
6. Gerber files
7. Pick-and-place files
8. Assembly files for PCB manufacturing
9. Basic firmware guidance or sample code
10. Suggestions for calibration and accuracy improvement
Important Notes
Accuracy is important, but the solution must still remain cost-effective.
Please suggest the best sensing method, such as CT clamp, shunt, metering IC, or any other suitable method.
We are open to your technical recommendation if you have already worked on electricity monitoring or energy meter PCB design.
The design should be suitable for future mass production.
We prefer a simple, robust, and practical solution rather than an overcomplicated design.
Please Apply With
When applying, please answer the following:
1. Have you designed any electricity monitoring / energy meter / power monitoring PCB before?
2. Which sensing method do you recommend for a low-cost industrial solution?
3. Can you design the PCB for JLCPCB or similar manufacturing?
4. Can you select components that are available from LCSC or similar suppliers?
5. What will be your estimated design time?
6. Can you share any similar previous work or portfolio?
We are looking for someone who can guide us technically and help us build a low-cost, reliable, industrial-grade IoT electricity monitoring device.
