DFRobot has launched the Fermion: BMV080, a low-cost air quality sensor module based on the Bosch BMV080. It provides fanless PM1, PM2.5, and PM10 sensing capabilities for $29.90. The sensor uses laser-based light-scattering technology and has a service life of up to 10 years. It measures particulate concentrations in a 0–1000 μg/m³ range with 1 μg/m³ resolution and supports I2C and SPI interfaces. It consumes about 70 mA in continuous measurement mode and 6 μA in sleep mode. The module also features a 35 cm obstruction zone for accurate readings. Schematics, component location diagrams, and 3D STEP files are available.
LEGO has unveiled a new 'smart brick' that can detect how it's being played with and react accordingly. This brick, developed in partnership with Wired, uses a combination of sensors and AI to understand building techniques and provide feedback. It's designed to inspire creativity and learning through play, offering features like pose detection, color recognition, and shape identification. The brick is part of LEGO's ongoing efforts to integrate technology into its building system, aiming to create more interactive and educational experiences.
OpenClaw is an open-source project that allows you to turn a Raspberry Pi into a capable AI agent. It provides a framework for connecting large language models (LLMs) to physical sensors and actuators, enabling the Pi to interact with the real world. This article details how to set up OpenClaw, including installing the necessary software, configuring the LLM, and connecting sensors like a microphone and camera. It also explores potential applications, such as home automation, robotics, and environmental monitoring.
This guide documents the setup of OpenClaw on a Raspberry Pi 5 w/ 8GB RAM and how to give it access to a TFT display, temperature/pressure sensor, USB camera, and NeoPixels. It uses eSpeak text-to-speech and Whisper Small speech-to-text to enable speech based communication with the bot.
An introduction to the ESP32 microcontroller for IoT projects, covering MicroPython and Arduino IDE programming.
This project walks you through building your own Inventory Robot that can automatically identify, organize, and track the components you use in your workspace. After finishing a prototype, placing every part back in the right spot can become time-consuming and difficult. This robot solves that by intelligently sorting and maintaining a clear inventory of your items.
This article details 7 ESPHome projects that enhance smart home functionality, including washing machine state detection, water leak detection, presence detection, Bluetooth proxy, custom smart speakers, cheap yellow displays, and ePaper dashboards.
Northwestern University engineers have developed VoxeLite, a bandage-like haptic device that achieves 'human resolution' in recreating touch sensations. It uses an array of tiny, individually controlled nodes to simulate texture and tactile sensations with high clarity, detail, and speed.
The SCD30 is a highly accurate CO2 sensor module based on patented CMOSens® Technology for IR detection, including a humidity and temperature sensor. It offers excellent long-term stability and easy integration into demanding applications, suitable for IAQ standards compliance.
The Adafruit Feather Bluefruit Sense takes the popular Feather nRF52840 Express and adds a comprehensive set of sensors, making it an excellent wireless sensor platform with Bluetooth Low Energy, native USB support, and Arduino/CircuitPython compatibility. It features environmental and motion sensing capabilities including 9-DoF motion sensors, proximity/light/color/gesture sensor, PDM microphone, humidity sensor, and barometric pressure sensor.
