Cooling down our cities

For urban heat islands, IoT heat sensors could be a catalyst. We can now affordably install IoT thermometers on buildings, in trees, on roads and in cars and buses to create a living, breathing map of the city's temperature. That will help identify where there are heat spikes and measure the effectiveness of attempts to cool things down. Remote measurements can also lead to responses to sudden heat spikes, such as automatically spraying water on the surface. What is measured is managed!
