If not sustainably manufactured or disposed of, the product could contribute to e-waste
Offer users control over data collection settings
Implement end-to-end encryption for all transmitted data
Require strong authentication for access to data and device settings
Design a user-friendly interface
Offer a low-cost or open source version for lower income users
Use recyclable or biodegradable materials
Design the device for easy repair and small upgrades
Offer take-back program and refunds to customers
Key electronic components (such as the ESP32, ACS712 sensor, or plug module) may degrade over time due to thermal stress, voltage fluctuations, or environmental factors (humidity, dust, etc.), which can lead to inaccurate readings or failure.
Continuous operation in confined spaces could result in overheating, especially if the device is plugged into high-load appliances, possibly leading to thermal runaway or even fire hazards
Software bugs or insufficient security updates might cause the device to provide inaccurate readings, maybe even expose vulnerabilities, potentially affecting user safety
Changes in power quality from the outlet (such as surges) could stress the electronics, reducing lifespan or causing inconsistent readings
Use high-quality, temperature-rated components and incorporate derating practices so that parts are not consistently operating at their maximum limits
Integrate passive heat sinks or ventilation openings in the design of the enclosure
Consider a thermal cutoff circuit that disconnects the device if temperatures exceed safe thresholds
Develop the firmware with rigorous testing, including stress and fault injection tests to simulate long-term use
Incorporate self-diagnostic routines that alert users to sensor drift or component failure
Include built-in surge protection circuits and voltage regulation to manage fluctuations
Use components that are rated for a range of input voltages and transient conditions as found in desktop power supplies
Ensure that all moving parts or connectors are robust enough to withstand repeated use without compromising safety or performance
Electronic Waste (E-Waste):
The device contains electronic components like sensors, microcontrollers (e.g., ESP32), and possibly a display or plug module. If disposed of improperly, these can contribute to toxic e-waste in landfills.
Non-Recyclable Materials:
If the device housing or internal components are made of mixed or non-recyclable plastics, they could persist in the environment for decades.
Battery Disposal Risk (if applicable):
If the device uses a rechargeable or coin-cell battery, improper disposal may result in chemical leakage or fire hazards.
Consumer Disposal Behavior:
Without clear guidance or incentives, users may throw the device in regular trash, increasing the likelihood of environmental harm.
Use Recyclable or Biodegradable Materials:
Design the outer casing with materials like ABS plastic or biodegradable polymers that are widely accepted in recycling streams.
Design for Disassembly:
Ensure the device can be easily opened to separate circuit boards, batteries, and housing for proper recycling.
Battery Safety Guidance:
Provide clear instructions for safe battery removal and disposal. Encourage users to take used batteries to designated recycling centers.
Take-Back Program:
Implement a take-back or recycling initiative where users can send the device back at the end of its life for responsible disposal or refurbishing.
User Education:
Include disposal and recycling instructions on the packaging and product manual to raise awareness and promote responsible behavior.
Modular Design for Repairs/Upgrades:
Allow users to replace or upgrade key parts (e.g., sensors or plug module) without discarding the entire device, extending its usable life.
