Use it to prototype an idea that needs camera images, movement, distance, or temperature and humidity. Start with simulated data, then connect a provisioned box over Wi-Fi. - [How to build an AI hardware demo](https://hardwareblocks.com/guides/build-an-ai-hardware-demo/) — Start with a simulated sensor in the HardwareBlocks web app. Publish a starter dashboard, then give your coding assistant the sensor schema and ask it to adapt the interface. Replace simulation with a claimed, connected device when the hardware is ready. No physical kit is needed for the first software demo. - [Build a room temperature and humidity monitor](https://hardwareblocks.com/guides/room-climate-monitor/) — Use the HardwareBlocks Climate Kit to measure temperature and relative humidity with one SHT31 module. Prototype the dashboard using climate.sample events, then read the same fields from a claimed Wi-Fi device. Any alerts or historical storage are application features you implement. - [Build a bike movement alert prototype](https://hardwareblocks.com/guides/bike-motion-alert/) — The HardwareBlocks Motion Kit can provide acceleration, rotation and a moving flag for a bike movement experiment. Your application decides when the bike is armed and when to notify you. The current kit needs Wi-Fi coverage; it is not a GPS tracker or a standalone theft alarm. - [Build a distance and object-presence demo](https://hardwareblocks.com/guides/distance-occupancy-sensor/) — Use a distance measurement and a calibrated threshold to prototype object presence. The HardwareBlocks Distance Kit uses a VL53L0X time-of-flight sensor and distance.sample events. Its API accepts 0–2,000 mm, but usable physical range depends on the target, light, mounting and sensor setup. - [Build an AI camera and fridge demo](https://hardwareblocks.com/guides/ai-camera-fridge-demo/) — Start with the HardwareBlocks Camera Kit for a private snapshot dashboard. To turn an image into a draft shopping list, your own backend retrieves the image, calls a vision model and asks the user to review the result. HardwareBlocks supplies the camera-data interface; AI inference is a separate integration. - [Development board comparison](https://hardwareblocks.com/compare/) - [FAQ](https://hardwareblocks.com/faq/)
