Altimeter One

This digital altimeter uses a highly accurate 19-bit barometric pressure sensor which can detect altitude changes of less than 30cms (1 foot)
Features:
1 channel - peak altitude
Sunlight-readable LCD display displays maximum flight altitude
Advanced rechargeable Lithium Polymer battery
Recharges in less than 2 hours from any standard USB port (cable included)
Highly accurate pressure sampling 25 times/second
Power button turns device ON/OFF and RESETs the display between flights
Automatically powers down to conserve power
Handy tether point allows secure attachment, or independent streamer recovery
Rugged ABS construction to survive crashes
“Realtime Altitude Mode” displays current altitude above ground level in real-time
Replaceable parts include battery, LCD, and case
Here are some of the more interesting ways in which the Altimeter One has been used:

- Tethered to the leg of a hunting falcon
- As an on-screen altitude display in RC planes
- In science projects (click here for one example)
- In world-record attempts for high altitude kite-flying
