Stratoflight's data logger STRATO3

The STRATO3 data logger was developed specifically for recording measurement data from stratospheric flights and records data up to 50,000 meters in altitude. This means that the secret of the flight altitude reached can now finally be revealed. The data is saved every 2 seconds on a microSD card and can be evaluated on the PC after the flight. Our online tool creates numerous graphs with just a few clicks and, as a special highlight, the flight route can be displayed as a 3D curve in Google Earth. The data logger offers the option of reading out the data for your own expansions via a serial interface. The included sensors can be attached outside the probe using a 30 cm long cable, so that the data logger is safely protected inside against the extreme influences of the stratosphere. Thanks to its lightweight design in credit card format, it is ideal for reaching maximum flight altitudes with the weather balloon. The operation is very simple, no programming knowledge is required.
Features - Recording of GPS coordinates, flight altitude, inside temperature, outside temperature, air pressure, humidity, rate of climb and descent, speed over ground - Unlocked GPS module: Saves the data up to an altitude of 50,000m.
