Sensorbox (handheld measurement terminal)
Project description
Sensorbox is handheld measurement terminal with embedded GPRS
connenctivity.
It is equiped in GPS receiver, LCD and keyboard, allows to connect up to
3 sensors or peripheral devices. They can be connected using 10pin RJ50
modular connectors.
Each of them can be:
- digital( SPI, UART or I2C)
- analog (0-3.3V)
System is based on Cortex-M3 microcontroller. Decice is supplied from 5V
via micro-USB connector.
Backup LiOn battery can be also used, charging circuit is embedded.
The device is equipped with power switch and matrix
keyboard.
