Yoctopuce Yocto - Altimeter
Just connect this sensor to a Sensor Hub connector device that connects to Valarm Tools Cloud via GSM, WiFi, or Ethernet. Then you can quickly and easily monitor remote sensor status on the web, and receive configurable email alerts for your telemetry.
The Yocto-Altimeter sensor device is a USB altimeter. It gives you an altitude estimate based on atmospheric pressure. The Yocto-Altimeter is precise enough to detect altitude changes as small as 25cm. It also gives you the current environment's barometric pressure and temperature.
This circuit has been designed so that the sensor itself can be moved further away from the USB connector by a few meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.
