Thunder & Lightning vs M2go Sensor

Thunder & Lightning has (barely) one practical purpose: to measure your distance to a sound source. It works for thunder and lightning, fireworks, rocket launches, or other loud events visible from a (hopefully safe) distance away. Just press the Lightning button when you see the event, and Thunder when you hear it. Modern technology does the rest. To perform this trivial task even more accurately, you can enter the temperature of your surroundings to more precisely calculate the speed of sound. You can also choose between U.S./Imperial and metric measurements depending on your personal unit preferences. Should its intended purpose be insufficiently useful, this application can also be used as a reasonably precise (if redundant) stopwatch, a speed-of-sound calculator, a Fahrenheit/Celsius converter, or as an odometer if you happen to be traveling at precisely the speed of sound. Note: Use of application while operating supersonic aircraft is not recommended or approved.

The M2go Sensor application works as a bluetooth smart sensor interface for the Measure2go hardware by taskit. This application lets you set up and calibrate the sensor nodes. It can store the displayed real time measurement values or download logged data over bluetooth to your mobile device. The stored data can then be exported. The connection to the Measure2go accessories is established via Bluetooth Smart (aka: Bluetooth Low Energy). Features: - Supports the following Measure2go sensors: Blue pH-Meter, Blue RTD, Blue LoopRX, Blue LoopTX - Download of logged data from sensor - Manual storage of measurement values - Change sensor configuration - Wireless communication with the sensor nodes over Bluetooth Low Energy (BLE) Display: The sensor value readings can be viewed in real-time including: - The unique sensor node ID - Digital sensor value display in any unit - Last stored measurement value with timestamp - Last calibration with slope, offset and date (on "Info" page) - Trigger to shot the current sensor value manually Storage / transfer: All stored readings (sensor values, pH, voltage, temperature, location and time) can be exported by e-mail or via iTunes as a csv file. This file can be imported to (nearly) any spreadsheet programm on the PC and then be viewed in a table. Compatibility: Requires iOS 9.0 or later. Compatible with iPhone, iPad and iPod touch.
