A sensitive air pressure sensor with sturdy connection for a range of common tube sizes. Suitable for general air pressure measurement, barometric pressure and sensitive enough for use as an altimeter.
Single Axis Linear Accelerometer. The linear accelerometer is a small robust sensor for measuring acceleration, including acceleration due to gravity. It is also able to detect tilt angle (relative to vertical), making it a useful general purpose tilt sensor.
Radioactivity sensor to measure the intensity of Radioactive sources. A very sensitive radioactivity sensor which can measure Alpha, Beta and Gamma emissions. With low power battery feature for long term half life experiments.
