Listening - Using sensors and data loggers for agriculture/Prompts

From OER in Education

Instrumentation for plant research - Roger Frost meets Tony Peloe from Delta-T

Delta-T supply plant and environment monitoring equipment, including data loggers, to plant growers and researchers.

  • How does the equipment made here generally differ from what you could buy more cheaply in a garden centre?
  • How does a ‘frequency domain’ moisture sensor work?
  • How is the sensor used and what value does it give?
  • Describe the use of the profiling probe which measures moisture at depth.
  • For what purpose is the profiling probe used?
  • What is their controller data logger able to do?
  • What advantage does this offer?
  • What does the solar pyranometer allow scientists to measure?
  • Why is measuring diffuse radiation from the sun of current interest? - Mention any current interest in measuring radiation.
  • Why might keepers of Roman ruins be interested in measuring moisture?
  • The sun ‘moves across the sky’ each day. How does the pyranometer – the device that measures radiation – manage to record it from a single location?
  • How can a temperature probe (thermistor) be used to measure a horses breathing?
