NextPCB Environmental Sensing Challenge: Build a Smarter Home that Thinks like You

Your current smart home is full of devices, but it's not truly aware. It reacts to simple commands but fails to proactively care for your comfort, health, and safety. Imagine this: It’s a crisp morning, and your smart blinds open to let in the sun. But an hour later, the room feels stuffy and too warm. Is it the humidity? The temperature? The stale air? You don't know because your smart home can't feel it. Every family cares deeply about the invisible environment—temperature, humidity, air quality, light, and security.

While Home Assistant has revolutionized smart homes by putting control back into users' hands, the true next step lies in the home's ability to perceive its environment accurately and act intelligently.

NextPCB, a leader in PCB and PCBA manufacturing, is launching this challenge to empower the community to build this next generation of environmental sensing devices.

What We Are Looking For

We encourage participants to think creatively within the broad theme of Environmental Sensing & Automation.

Suggested Project Directions (for Inspiration)

Here are three technically interesting and universally relevant directions:

The High-Precision, Multi-Sensor Environment Monitor
Concept: Design an elegant, single PCBA that integrates sensors for PM2.5/PM10, VOC, eCO2, Temperature, Humidity, and Barometric Pressure.

The 24/7 Presence Detector using mmWave Radar
Concept: Develop a highly reliable presence sensor using mmWave radar (e.g., Infineon's XENSIV™ or similar) that can detect subtle movements like breathing, moving beyond the limitations of standard PIR sensors.

The Distributed Water Leak Detection Network
Concept: Build a network of small, wireless (e.g., Zigbee/Thread) water leak detectors to be placed in multiple risk areas.

How to Enter and Win

Prize: We will select 5 winning projects. Each winner will receive $500 USD in PCB Assembly credit from NextPCB to bring their innovative design to life.

Steps to Participate:

1. Submit your project plan here, including a project overview, a list of key components, and your intended integration with Home Assistant.
2. You will receive a confirmation email once your plan has passed the evaluation.
3. Once evaluated, get PCBA units completely free.

Deadline for Submission: 30th November 2025
