A sensor is a device thatmeasures a physical quantity <strong>and</strong> c<strong>on</strong>verts it into a signal that can be read by an observeror by an instrument such as <str<strong>on</strong>g>data</str<strong>on</strong>g> logger c<strong>on</strong>nected to a computer.Data logger used: USB linkThere are several types <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>data</str<strong>on</strong>g> <str<strong>on</strong>g>loggers</str<strong>on</strong>g> which can be used indifferent educati<strong>on</strong>al c<strong>on</strong>texts (inside or outside the classroom). The<str<strong>on</strong>g>data</str<strong>on</strong>g> logger used for the pilot activities was a USB Link, allowing tomake computerized experiments in the classroom <strong>and</strong> to plug from<strong>on</strong>e to four sensors into the computer at the same time.Temperature (sensor DT029)IMAGE 1: USB <str<strong>on</strong>g>data</str<strong>on</strong>g>logger c<strong>on</strong>nected toa laptop <strong>and</strong> a sensorThe temperature sensor measures temperature between -25°C<strong>and</strong> 110°C. It can be used as a thermometer for experiments inchemistry, physics, biology, earth <strong>science</strong> <strong>and</strong> envir<strong>on</strong>mental<strong>science</strong> <strong>and</strong> is mostly suitable for water <strong>and</strong> other chemicalsoluti<strong>on</strong> temperature measurements.Heart rate (sensor DT155A)The heart rate sensor m<strong>on</strong>itors the light level transmitted throughthe vascular tissue <str<strong>on</strong>g>of</str<strong>on</strong>g> the fingertip <strong>and</strong> the corresp<strong>on</strong>dingvariati<strong>on</strong>s in light intensities that occur as the blood volumechanges in the tissue. It has two ranges: waveform <strong>and</strong> beats perminute. The heart rate sensor measures heart rate between 0 <strong>and</strong>200 bpm (beats per minute).IMAGE 2:Temperature sensorIMAGE 3:Heart rate sensor15
