I am working on a project to send an Arduino up to high atmosphere with a weather balloon. I just got the board and all of the sensors working (powered by USB) and am starting the process of determining the battery requirements for the whole thing.
I tried using a 9 volt battery and while it powered the Arduino for about 15 hours, there was no data from the sensors written to the file on my SD card. The sensor data writes just fine when attached to USB power.
Here are the sensors I am using (they are all using 5V power):
(2) Tmp36 Datasheet
ASDX pressure sensor Datasheet
Adafruit digital UV/IR sensor Datasheet
SainSmart Micro SD Storage Board SPI For Arduino (Datasheet not available - used these directions to install and program
I am still working on attaching these sensors but they are not currently part of my sketch. If anyone has any info or experience with these sensors, I would appreciate any info you might have.
DE-ACCM6G Accelerometer Datasheet
HIH4031 humidity sensor Datasheet With this breakout board Datasheet
I’ve attached our sketch if you would like to take a look.
TL;DR - Need help determining what kind of battery for my project - sensors are all 5V and 9V battery powers but writes no data to SD card.
Thank you all in advance!
