Components for my balloon satellite project

Currently on my satellite i have components such as camera, GPS, UV sensor,9 degree of freedom ,Humidity and Temperature Sensor Breakout - HIH6130(however im currently looking for a better humidity sensor. Is there a better humidity sensor at the market right now? need a sensor with quite a number of arduino codes.

Also anyone have any ideas of what additional components that can be added to my project?

  • Ultrasonic sensor cant be use as it has a 4m limitation

The SHT31-D breakout board from Adafruit works quite well. They have a good library and example.

Was thinking what is the difference between sht15 and sht31 and which do u think is better?

Not sure about the SHT15 but the SHT31 uses I2C to communicate and has a software controlled heater for bakeout, if needed. I tried it and it takes 3 minutes to bake and 2 minutes to recover. I guess you would use it if the sensor had been sitting in a very moist environment unpowered for a long time. It also has some kind of controllable internal averaging for more stable readings. The Adafruit page talks about it's features relative to earlier versions.
