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.
This sensor features a new design digital light switch which has an integral light guide to be used for counting and timing events which make or break an IR visible light sensitive path.
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.
