Cogent House is a system for sensing temperature, humidity, CO2, Air Quality, VOC, hot water consumption, and electricity consumption within the home. It has been developed by the [http://cogentcomputing.org Cogent Computing Applied Research Centre] at Coventry University. Cogent House is developed using TinyOS and Python.

Review phase one/two sensing #99

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The phase one / two sensing needs reviewing to decide which sensing modality 
goes in which phase.

Phase 2 sensing is for long duration, energy consuming sensing such as CO2. 
Passive sensors such as temperature and humidity can go in phase 1. 

The main aim of splitting phase 1 and phase 2 sensing is to avoid self-heating 
during the sensing phase affecting any temperature or humidity measurement. 
However the phase split could be used to distinguish other types of sensors 
that are somehow incompatible. In general, if a sensor is not incompatible with 
another sensor type, it should be in phase 1. 

Note that phase 2 will be trivial in the case that no ph2 sensors are active.
