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.
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.
