During the London citizen cyberscience summit, there was a workshop about thermal flashlight by Shannon and Sara.

We made a great thermal sensor using an Arduido kit, a circuit board, a thermometer, a RDB LED, resistors, a capacitor, a battery, and lots of wires. I'm not good at electronics, but it just worked. You can make the sensor more sensitive with a different range for the LED colors.

After making a sensor, we captured thermal images using the sensor and a laptop (with a web cam) from

You can see several images inside of Room 121, Chorley Institue, UCL. The room was the darkest one we could find around here.

We tried to capture thermal images with two different ranges for different LED colors. Basically, the blue color means low temperature while the red color means high temperature.

You may recognise David (Zhiwei), Paolo and Seong on the images. Thanks, Shannon and Sara!! It was a great experience and experiment.


Hi Seong, Thanks so much for posting this note! Could you tag it with Thermal Flashlight so it is organized with all of the other research notes on the Thermal Flashlight?

Also let's follow up over email to figure out using the Thermal Flashlight around London?

Is this a question? Click here to post it to the Questions page.

hi! 7 years later, i tagged this post with thermal-flashlight :)))
