SENSORS
Respiration Rate Sensor PS-2133
Includes respiration belt and sensor.
Salinity Sensor PS-2195
Soil Moisture Sensor PS-2163
Explore human respiration or study how respiration rate is affected by exercise, temperature variation, and other factors. Use in combination with the Heart Rate Sensor to explore correlations between heart rate and respiration rate.
THE TEACHING ADVANTAGE
A Pressure sensor worn on inflatable belt around ribcage or waist provides convenient hands- free use
A Measures changes in pressure caused by expansion and contraction of the chest cavity
THE TEACHING ADVANTAGE
A Built-in calculation to compensate for the change in conductivity due to temperature change
The Salinity Sensor measures salinity, conductivity and temperature, and determines salinity based on electrical conductivity. Great for exploring the salinity of local water sources or measuring the change in salinity of saltwater as it evaporates.
Just how dry is that soil sample and how does it affect your vegetation? Measure the water content of soil in percent. Measure changes in soil moisture around plants over time, study evaporation, and determine optimum moisture conditions for different species of plants.
THE TEACHING ADVANTAGE A Pre-calibrated for common soil types
A Ideal for environmental science, agricultural science or biology
How does your respiration rate change during physical activity?
Quickly determine the moisture in your soil or leave for a time to see how quickly soil moisture changes.
Build your own calculation: find breath rate or measure the time between breaths.
