hmt-3cha - Handheld measurement terminal

Subject: Handheld measurement terminal

Description: It is a simple, low-cost measurement device equipped with GPS, GPRS modem, keyboard, display and LiOn battery. It can be also supplied/charged via a USB connector.
It is enclosed in a nice-looking Hammond enclosure. It also has 3 RJ50 connectors that enable connection of various types of sensors.
Each sensor can be connected using UART, I2C, SPI, 1-wire or analog interface. The device connects with a remote server which is also part of the development.
We want to use them at Warsaw University of Technology to build a distributed network of sensors.
