What is Terra IoT System?

The Terra system implements a high-level programming environment to support development of IoT/WSN systems. Basically, Terra System is composed by a small virtual machine that is programmed using a reactive scripting language. A Terra developer can customize the VM interfaces to access hardware specific resources. Terra was built originally targeting devices based on small micro-controllers and very simple radios, but currently we have versions running also in Linux and Android machines. The Terra Site presents detailed informations about Terra.

Current platforms summary

Summary of current supported platforms and/or operational system. The menu Platforms presents detailed informations for each platform implementation.

All platforms implement a minimal support that includes the virtual machine engine, radio communication, and access to a very simples hardware like LEDs or temperature sensors. The Dev.Status column indicates some additional or special implementation for specific platform.

Platform Name MCU/CPU Protocol/Radio Dev. Status
TinyOS 8/16bits, 4/8MHz, 4/8/10KB RAM IEEE802.15.4 and 900MHz LEDs, Luminosity, and Temperature Sensor. Optionally a Group Communication library
Linux/RPi RPi or Linux box UDP/WIFI
Android Android devices - tested in 6.0 version (API 24) UDP/WIFI Screen - Touch and Set Color
ESP8266 32bits, 80MHz, 96KB RAM UDP/WIFI LED and Temperature Sensor
ArduinoMega ATmega2560 - 8bits, 16MHz, 8KB RAM Proprietary/NRF24L01+ LED and Temperature Sensor


Source Code

Terra IoT is licensed under the terms of the GPLv3 license.

The system is composed by some modules and tools found at Terra Repository. The Platforms Menu presents informations about the implementation and the build process for each platform.

Terra pre-built environment

Terra IoT system was pre-installed in an Ubuntu Linux virtual machine to support teaching/learning and application development. Tutorial and the download can be found at Terra Site.
