In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

We tested the use of piezo-resistive force sensors to measure bite force in small mammals. These force sensors are thin (less than 1 mm) and can be used to measure forces up to 4,500 N. A ...

The [Libelium] team wanted to help people in Japan measure radiation in their surroundings following the nuclear accident in Fukushima. Because of the affordability and seeming ubiquity of the Arduino ...

HDK-America has announced an incredibly small, piezo-resistive three-axis acceleration sensor. HDK-America has released a small, piezo-resistive three-axis acceleration sensor, the HAAM-325B, ...
