1170 - Wireless Oxygen In Air Sensor Manual

The Oxygen In Air Sensor can be used to investigate a number of scientific experiments such as:

• Human respiration – compare oxygen levels in inhaled and exhaled air.
• Respiration before and after exercise – investigate changes in oxygen consumption following physical activity.
• Photosynthesis – measure changes in oxygen concentration as plants photosynthesise.
• Plant respiration – investigate oxygen consumption by plants in darkness.
• Effect of light on photosynthesis – investigate how light intensity, colour or duration affects oxygen production.
• Effect of temperature on photosynthesis – investigate how temperature affects the rate of oxygen production.
• Germinating seeds – measure oxygen consumption during respiration.
• Yeast respiration – investigate oxygen consumption under different conditions.
• Insect respiration – measure oxygen consumption as an indication of respiratory activity.
• Animal respiration – investigate respiratory rates by monitoring oxygen consumption.
• Fruit and vegetable respiration – compare oxygen consumption under different storage conditions.
• Soil respiration – investigate biological activity by measuring oxygen consumption.
• Decomposition – monitor oxygen consumption during the breakdown of organic material.
• Catalase and hydrogen peroxide – measure oxygen production as catalase decomposes hydrogen peroxide.
• Combustion – investigate the decrease in oxygen concentration during burning.
• Air quality – monitor oxygen levels in different environments.
• Environmental investigations – investigate oxygen changes alongside temperature, humidity and pressure.
• Sealed ecosystems – investigate changes in oxygen associated with photosynthesis and respiration.

Combined Oxygen and CO₂ Experiments

Using the Oxygen in Air Sensor together with a CO₂ Sensor provides simultaneous measurements of oxygen and carbon dioxide, allowing a more complete investigation of gas exchange:

• Photosynthesis – measure the increase in O₂ and decrease in CO₂ as plants photosynthesise.
• Plant respiration – measure the decrease in O₂ and increase in CO₂ during respiration.
• Light vs. dark experiments – observe the switch between photosynthesis and respiration by monitoring both gases.
• Effect of light intensity – investigate how changing light levels affects both O₂ production and CO₂ consumption.
• Effect of temperature – investigate the effect of temperature on photosynthetic and respiratory activity.
• Human respiration – simultaneously measure O₂ consumption and CO₂ production during breathing.
• Exercise and respiration – compare O₂ consumption and CO₂ production before, during and after exercise.
• Insect and animal respiration – measure both oxygen consumption and carbon dioxide production.
• Germinating seeds – monitor O₂ consumption and CO₂ production during respiration.
• Yeast respiration – investigate changes in O₂ and CO₂ under different temperatures or nutrient conditions.
• Fruit and vegetable respiration – compare respiratory activity by monitoring both gases.
• Soil respiration – measure O₂ consumption and CO₂ production as indicators of biological activity.
• Decomposition – investigate gas exchange during the breakdown of organic material.
• Combustion – monitor O₂ consumption and CO₂ production during burning.
• Sealed ecosystems – investigate the balance between photosynthesis and respiration over time.
• Air quality – compare O₂ and CO₂ concentrations in different environments.
• Environmental studies – investigate how temperature, humidity and pressure relate to changes in O₂ and CO₂.
