 3.3V HAB Detail

Ready for sell now    23 Jun 2014  Detail

This project is used for  balloons to explore the edge of space. Collecting temperature, humidity, altitude, pressure data sending back through a FM Transmitter and saving all logs into the SD card. Also it can take a photo every 30secs  and then saving it  into  the SD card.


The project use

1. ublox-7Max GPS module

2. Radiometrix NTX2B 434.xxx Mhz 10mW modules.

3. TMP102 temp sensor to monitor Raspberry Pi temperature

4. BMP085  Barometric Pressure/Temp/Altitude Sensor

5. DHT22   / AM2302  Digital Temp & Humidity Sensor

   or i2c HTU21D   Digital Temp & Humidity Sensor

6. DS18b20 Temperature sensor

7. TRACOPOWER 5V & 3.3V (TSR-1-2433 & TSR-1-2450) DC/DC converter

  (DC input Min 6.5V )

    up to 96% efficiency - No heat-sink required ( for longer battery life)

     5V provide to Raspberry Pi & Rs Pi P-HAB module board

 Test 1 in Normal Freezer   -24 degree Celsius    6 x AA Energizer Lithium 

           --  5 Hours 10 mins

8. Raspberry Pi Camera kit ( take photos save into SD card)







GPS antenna & FM antenna &

USB SDR Encoder (RTL2832U-based DVB-T devices (RTL-SDR)


the eduhab.py send GPS location, tmp102, DS18B20, BMP085, DHT22 information through FM UHF Transmitter,  the eduhab.py have 3 commands

eduhap.py -s   short data stream mode  send GPS location and BMP085 Temp only ,

                        but all logs save to SD card

eduhab.py -p             send data  also take photos every 30sec

eduhab.py -c  prid      change the data stream "twick" to "prid"

  Tracking using a SDR software defined radio (SDR)


  Run sdrsharp.exe and you will see the following window:




 open DL-Fldigi, click Configure → Sound Card Click Capture → SDR(Virtual Audio   Cable)

  You should now be able to click on the payload as normal and decode :
