Handheld measurement terminal

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.
