For research purposes, "Dr Ayars" and some students came up with a huge two-dimensional temperature measuring device. Using a 30cm sqare piece of aluminium they mounted one hundred DS18B20 temperature sensors - all of which can be read by an Arduino. Once the measurements have taken place, the data can be sent out to a PC to be analysed by all sorts of software. Their example using python code created a usable colour temperature display. A fine example is shown below, where a bag of ice and a soldering iron are placed near the sensors:
Although measuring temperature and humidity is nothing new, have you done so with an Infrared temperature sensor module?
The new Freetronics IRTEMP: module is perfect for contactless temperature measurement. This is our special version of the industrial infrared remote thermometer units with an onboard power supply, communication support and a software library and examples supplied. Very simple to use with an Arduino as we have provided a Getting Started guide and Arduino library. For more information and to order, click here.
