Sensors
We are excited to announce that the final sensors have been selected for ArduSat!
After our high altitude balloon tests and a lot of work our team has completed the selection of the instruments that will be used on our first satellite. We want to show you exactly what will be flying on the satellite you are make possible!
Freescale's MAG3110, small and low powered this digital 3-axis magnetometer will allow the satellite to measure the earth's magnetic field. We put together some introductory informational videos for you at these are the MAG3110 series of videos. The data sheet is available from
http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Magneto/MAG3110.pdfInvenSense's ITG-3200, this compact 3-axis digital gyro will sense the satellites movements. It is a robust instrument that is also small and sensitive. The datasheet is available at
http://www.sparkfun.com/datasheets/Sensors/Gyro/PS-ITG-3200-00-01.4.pdf.
Analog Devices's ADXL345 is a small, low power 3-axis accelerometer. Highly sensitive the accelerometer will be used to track the acceleration of the satellite. The full details about the sensor can be found here:
http://www.sparkfun.com/datasheets/Sensors/Accelerometer/ADXL345.pdf. Next is the
Melexis's MLX90614 infrared temperature sensor which has a wide sensing range. The sensors can be used to measure the emissivity of the earth for more information on potential uses of the sensor please see the incormational video series MLX90614 on NanoSat_University. The full details about the sensor can be found here
http://www.sparkfun.com/datasheets/Sensors/Temperature/SEN-09570-datasheet-3901090614M005.pdf.
Texas Instrument's TMO102 is a low power digital temperature sensor. Several of these will be used to track the internal and external temperature of the satellite. The full details about the sensor can be found here:
http://www.sparkfun.com/datasheets/Sensors/Temperature/tmp102.pdf.
LND, Inc.'s LND 716 Geiger counters will be used to monitor the radiation environment of the satellite. With a large range these small sensors will provide valuable data. For their specifications please see the manufactures information sheet here:
http://www.lndinc.com/products/pdf/306/. Additionally, we will publish more videos on how to use this sensor soon, especially as we upgraded your sensor-suite to include two(!) geiger-tubes in orthogonal configuration for more interesting experiments.
Adafruit Industries's TSL2561 luminosity sensor covers both infrared and visible light. These sensors will be placed beside the camera and the spectrometer to help you use those powerful and more complex sensors. For the full sensor details please see the data sheet here:
http://www.adafruit.com/datasheets/TSL2561.pdfMySpectral's Spectruino is our optical spectrometer specifically designed to work with Arduino. The details of the sensor are available at MySpectral's website
http://myspectral.com/ and we will provide instructional videos around how to best use this sensor soon.
And then there is our camera, which was upgraded to a 1.3 MP camera so you will be able to shoot pictures from earth with 4x the resolution from the camera we had originally planned for you!
As you know, we have developed some initial educational videos for the sensors. We also have some videos that explain a little bit more about the basic principles of how the data is handled on board the satellite.
These are set up at
www.screencast/users/Nanosat_University/. In the first set of files BMP085, Lara will walk you through the basic principles of the 12C bus using BMP085 as an example. The Datalogger series will walk through several of the principle involved in using Arduino for ArduSat. In MCP3424 Lara will go over the basics of how the analog to digital converter works. The remaining two series are for two of our sensors. Please use those videos and tell us what you like, dislike and what else you would like to see.
Over the coming days and weeks we will continue to put up more instructional videos and more capabilities to help you develop your code. We want to make it as simple and easy as possible and are working on some exciting developments for you. Stay tuned!
Last but not least, we’d also like to let you know that in case you do not get ready for your experiment for the July launch, we will give you all your time on the September launch to run it there. And if that is still not quite working out for you and in case (which we really hope) we launch further ArduSats in 2014, you will still be able to get your time to run your experiment there, free of charge. We promise to do whatever we can to get you and your amazing ideas into space!
