Sensors in the city

Warmer houses Pt.1

The Eltek GC-05 is a key part of the Insulation Retrofit project that is looking at how to better insulate public housing across Glasgow.

Sensors will be used to measure ambient temperature and relative humidity levels within the properties that have had insulation installed. The aim of this is to demonstrate that: a) the insulation is helping to reduce energy consumption; and b) that the conditions within the house have not been negatively affected and condensation levels are at an acceptable level.

This allows the Glasgow City Council and Housing Associations to better match insulation systems to different house types, allowing them to make smarter investment decisions. This information can also be made available to private householders to help them choose the best insulation for their home.

Warmer houses Pt.2

A lower cost, locally-developed sensor with a big role in the Insulation Retrofit project is the BuildAx sensor.

As with the Eltek GC-05 this sensor measure ambient temperature and relative humidity levels. This was a sensor developed by the University of Strathclyde and deployed in parallel to the Eltek GC-05. The sensor is lower cost than the Eltek GC-05 and has been developed to create a lower cost monitoring solution that will allow more properties in Glasgow to be monitored.

Responsive lighting

As part of the Intelligent Streetlighting project, we will be able to dim lights based on need. The SELC RF Mesh enabled Photo-Cells, measure ambient lighting levels and trigger the adjustment of lighting schedules and dimming profiles set through a Central Management System.

Use of this sensor could have a big impact on energy savings and the improve the lifecycle of our street lights.

Smart road lighting

As part of the Intelligent Streetlighting project, adaptive lighting control of LED lighting will be provided through a range of sensors.

One such sensor is the Citilog XCAM TD+ video sensor. Able to measure traffic and pedestrian footfall volume, data from the sensor means lighting levels can be adjusted according to need. This could have huge benefits to both lighting efficiency and public safety through a better understanding of our lighting needs.

Tracking noise

The Urbiotica U-Sound sensor monitors continuous sound levels in real time, notifying the Operations Centre when noise exceeds certain levels. The Operations Centre can then adjust lighting levels if desired through a Central Management System interface.

A system such as this could be used to enhance public safety by increasing visibility in areas where there is heavy footfall after an event or in an emergency situation.

Air pollution

Rethinking how we use the ‘real estate’ of our street lighting, the Urbiotica U-Air Sensor plugs into street light and can measure pollutant gases through chemical and optical sensors.

This information is brought back to a Central Management System that can trigger notification alerts if levels reach past predetermined thresholds. Being able to understand city air quality in real time build an accurate picture of pollution in the city and help us manage this in smarter and more effective ways.
