The BBC micro:bit is a pocket-sized computer that lets you get creative with digital technology. You can code, customize and control your micro:bit from anywhere! You can use your micro:bit for all sorts of unique creations, from robots to musical instruments and more. At half the size of a credit card, you will be surprised at the amount of hardware each board is equipped with, including 25 red LED lights that can flash messages. There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. The micro:bit can even detect motion and tell you which d..
The CCS811 is a sensor for detecting the level of carbon dioxide (CO2) and Total Volatile Organic Compounds (TVOCs) in the air. TVOC combined with CO2 is used to measure indoor air quality or IAQ. CO2 is produced by human respiration, and VOCs come from construction materials (paint, carpet, etc), machines (copiers, processes, etc), and people (breathing, cigarettes, etc). VOCs are often categorized as pollutants and/or sensory irritants.
TVOC is a roughly defined term, and we’re still wrapping our heads around what this sensor can do. Effectively, it can give you the parts per million (PPM) ..
This accelerometer board will allow your .NET Gadgeteer project to measure the force of acceleration. That’s actually a pretty neat trick, since it can be used to detect static forces, like the constant force of gravity, or dynamic forces caused by moving or vibrating the device.
Microsoft .NET Gadgeteer is an open-source toolkit for building small electronic devices using the .NET Micro Framework and Visual Studio/Visual C# Express. This module is designed to quickly and easily integrate into any .NET Gadgeteer project.
Dimensions: 17mm x 32mm
Did you lose some of your Gadgeteer cables? Or maybe you just built your own super awesome Gadgeteer module or breakout and need a cable to hook it up. Never fear, we sell them by the 10-pack! That’s right, 10 of these wonderful 10cm long .NET Gadgeteer compatible cables so you’ll always have enough on hand...
The MLX90393 is a tri-axial magnetic sensor capable of sensing very small fields (like the Earth’s magnetic field) while behaving as one would want and expect during saturation in larger fields (like a near by magnet). It turns out the favorite HMC5883L and other such sensors that are intended for compass applications have a low dynamic range but also strange and undefined behavior in large fields. Ted Yapo did an incredibly extensive characterization of the sensor over on Hackaday. He published his controlled experiments testing a few sensors and found the MLX90393 to be superior.
The PocketGeiger-Type5 from Radiation Watch is a highly sensitive radiation sensor designed for the embedded systems market. Capable of detecting Gamma and Beta radiation, it has a simple pulsed output that can be used with any microcontroller. The Pocket Geiger has an onboard DC boost circuit, so the board can be supplied with a friendly 3V to 9V. Using only 30mW (10mA @ 3V), it is very low power. Radiation Watch has a handful of documents and example Arduino code to get you up and running. They have also written a Windows example program written in C# (source included!) to output graphs to a..
Does your robot crush objects with its hulkishly strong grip? Give your robotic hand or claw a better sense of touch with the Robotic Finger Sensor.
The Robotic Finger Sensor (RFS) uses a unique combination of infrared distance sensing, optical encapsulant and data filtering to detect extremely light touches. Additionally, the silicon covering is squishy, giving the sensor increased grip (friction) and a qualitative sense of force; the sensor can’t output a quantitative number like 2.7 lbs of force, but it does output an increasing IR value indicating additional compression of the encapsulant..
