Light Logger Sensor NUL-204

Light Logger Sensor NUL-204

This sensor is very versatile with applications in many areas of the natural sciences. It can be used to study photosynthesis in biology, light-emitting chemical reactions in chemistry, the effect of changing voltage on a light-bulb’s output in physics and more.

This sensor measures illumination with three ranges; it can be used in low light environments such as in a classroom, or high light environments as in daylight outdoors.

With both fast and slow modes, it can be used to measure fast light changes such as those produced by light bulbs connected to an AC supply, as well as the almost steady levels outside on a sunny day.

The light sensor in located in a plastic box just behind an access hole.

Specifications:

Experiment Duration: 50 milliseconds to 31 days.

Heart rate & pulse logger sensor NUL-208

Heart Rate & Pulse logger sensor NUL-208

This sensor can be used to monitor and compare pulse rates under various exercise and rest conditions. Additionally, it can show changes of blood volume/flow in the finger or ear lobe with time.

The sensor has two modes of operation: measuring the BPM (Beats per Minute) of the heart rate or displaying the analog arbitrary value of the measured signal.

The electrodes are both plethysmograph-based. The sensors consist of an infrared LED transmitter and a matched infrared phototransistor receiver.

For best results, the sensor should be kept away from direct sunlight and high intensity lights. The student whose pulse is being measured should be still without moving as much as possible.

Specifications (BPM stands for beats per minute):

Experiment Duration: 1 seconds to 31 days.

GSR logger sensor NUL-217

GSR logger sensor NUL-217

The Galvanic Skin Response (GSR) logger sensor measures the conductivity of our skin, especially of our fingers.

The conductivity of our skin changes according to unconscious emotion effects such as sudden noise, smell, touch, pain or view.

This sensor has two ranges: conductivity in microsiemens and arbitrary numbers.

Specifications:

Experiment Duration: 1 seconds to 31 days.

Force plate logger sensor NUL-225

Force Plate logger sensor NUL-225

This module is in fact a weight scale designed for a multi range of purposes. Simply lay a heavy weight on its surface, or activate a forceful pressure against it (like a bouncing ball), and the logger sensor will measure it. But that’s not all, once a special set of handles are attached, it can also measure pull pressure rather than just weights and presses.

Specifications:

Experiment Duration: 1 second to 31 days.

Force logger sensor NUL-211

Force logger sensor NUL-211

This sensor can measure the mass to weight relationship and study how different pulley systems affect the effort needed to lift weights. It can also be used to measure push/pull forces and impacts. There is a hook at the bottom of the force sensor that can be connected to various pulling loads.

The sensor can be hung from a universal laboratory stand via a rod through the hole in it.

This sensor can be operated facing upwards, downwards or at any intermediate (including horizontal) position.

Sensor zeroing

After connecting the sensor to a power source (battery module or USB module and PC), hold the sensor in its proper position and press the button in the sensor’s box for about 3 seconds.

Specifications:

Experiment Duration: 50 milliseconds to 31 days.

Flow logger sensor NUL-224

Flow logger sensor NUL-224

This sensor allows for a stream of water to flow through its inlet and outlet pipes, thus revolving a rotation wheel within it. The wheel is not connected mechanically to anything else, but rather floats on a bearing for minimum friction and the enhancement of its minute accuracy. The measuring is done by monitoring changes in the sensor’s surrounding magnetic field.

Specifications:

Experiment Duration: 1 second to 31 days.

Electrocardiogram logger sensor NUL-218

Electrocardiogram logger sensor NUL-218

Identical in its use to a regular medical ECG (electrocardiogram), this is a rather simple three lead based logger sensor. It presents a heartbeat graph that allows a thorough examination of the heart’s electrical activity from three different angles. Unlike most ECG devices, this unit operates with non-disposable electrodes

Specifications:

Experiment Duration: 1 second to 31 days.
