Humidity, Temperature vs Pressure

SOhio 2017-1 Stratospheric Sense HAT data (pt 1) Pressure, Humidity, and Temperature

Introduction On the morning of August 12, 2017 I and my co-conspirators flew a High Altitude Balloon mission out of the Wyandot County Airport, near Upper Sandusky, Ohio.  One of the goals of this mission was to show we could operate a Raspberry Pi throughout the flight.  I had hoped to fly an SHT31A Humidity … Continue reading SOhio 2017-1 Stratospheric Sense HAT data (pt 1) Pressure, Humidity, and Temperature

High Altitude Balloon Humidity Measurement Methods

Abstract This is a survey of humidity measurement methods and some of the solid state devices available to perform humidity measurements. I am looking for methods suitable for making stratospheric balloon sounding dew point measurements. I intend to try this using an SHT-31A breakout board from ClosedCube. This sensor should be able to see the … Continue reading High Altitude Balloon Humidity Measurement Methods
