TinyOS TinyOS is a small micro-threading operating system that abstracts core application development from specific hardware details The design methodology is to 'wire' different components to each other – higher level components call 'tasks' in lower level components, and lower levels signal 'events' to higher levels

TinyOS

Sleep Mode – Power Conservation Query Mode – Data Acquisition Re-Programming Mode – Future Option Modes of Operation

–Environmental Conditions -20 – 80º C 0 – 100% Relative Humidity (RH) –Sensor Accuracy Light Sensor: ±10% Lumens Humidity: ±3% RH Temperature: ±3º C –Power Usage 3.3V Operating Voltage Goal: 6 Month Battery Life Specifications
