The module automatically searches for the connected sensors and displays one of them digitally. Scrolling for displaying the reading of another sensor is done by pressing the pushbutton switch on the display module.

This sensor is based on a thermocouple sensor that enables measuring very high temperature levels, even the temperature of a flame, as well as very low temperature levels.

This sensor has two modes of operation: Celsius and Fahrenheit.

Experiment Duration: 1 seconds to 31 days.

Logger sensor Guide

This sensor measures voltages across various resistive, capacitive and inductive components, as well as those of photovoltaic cells, batteries and power supplies. This sensor can also be used to measure electrode potentials and to investigate the charging and discharging of capacitors.

When used in conjunction with the, the dependence of the current flowing on the applied voltage can be studied in various electric circuits.

This sensor can be used to measure low voltage AC and DC circuits. With its 4 mm plugs, it can easily be connected into electric circuits.

It can also measure, using a step-down transformer, the AC voltage of the main supply and check its frequency 50/60 Hz (the input is limited to ±20 V).

There are different wavelengths of ultra violet light. The UVB wavelength range is 280-320 nm, which is 2% of the total UV radiation. The UVB radiation affects the vitamin generation in the human body, the immune suppression, skin cancer and cataract. The intensity of this light is measured in mW/m² (milliwatt per square meter).

Specifications:

Experiment Duration: 1 seconds to 31 days.

There are different wavelengths of ultra violet light. The UVA wavelength range is 320-370 nm, which is 98% of the total UV radiation. The UVA radiation affects photoaging and also photochemical smog. The intensity of this light is measured in mW/m² (milliwatt per square meter).

Specifications:

Experiment Duration: 1 seconds to 31 days.

Logger sensor Guide

This sensor measures the reflected light that enters into a tube containing a solution. As solution turbidity is higher, more light is reflected and measured by the light sensor, located perpendicular to the light source.

The turbidity measurement units are Nephelometric Turbidity Unit (NTU).

Specifications:

Experiment Duration: 1 seconds to 31 days.

Logger sensor Guide

This is one of our most versatile sensors. It can be used in biology to monitor ecological systems, microbiological cultures and to study the effect of temperature on photosynthesis and enzymatic reactions. In chemistry, to study exothermic or endothermic reactions and how the rate of reaction is affected by temperature; in physics it can be used to study heat/energy transfer.

The sensitive element is within a 180 mm long, 3.2 mm diameter stainless steel tube. This sensor can be used for temperature measurements in solids, liquids or gases.

Specifications:

Experiment Duration: 1 seconds to 31 days.

This sensor has two modes of operation. In slow mode it can be used to measure sound-pressure level in decibels. In fast mode it can display waveforms of different sound sources such as tuning forks and wind-chimes so that period and frequency can be determined. With two sound sensors, the velocity of propagation of sound in various media could be determined by timing a pulse travelling between them. The sound sensor is located in a plastic box accessible to the atmosphere via a hole in its side.

Specifications:

Experiment Duration: 25 milliseconds to 31 days.

Logger sensor Guide

This logger sensor is based on measuring the partial vacuum pressure in a tensiometer. A tensiometer is a closed tube with a special ceramic part in its end. The tensiometer is filled with water and put in the soil. If the soil is dry, water goes out by diffusion through the ceramic holes and partial vacuum pressure is created in the tensiometer. When we wet the soil, the partial vacuum in the tensiometer pulls water into the tensiometer and the vacuum decreases. This is why soil moisture is measured in pressure level.

Experiment Duration: 1 seconds to 31 days.
