How You Can Have Mosquito Vision

If you've ever been outside on a summer night, then come indoors to find you've been attacked by bloodthirsty mosquitoes, you know that those little buggers must be able to see in the dark. In fact, mosquitoes use infrared light to hone in on our body's heat in order to find our juicy bits.

Infrared light also is the same light that most television remote controls use for sending signals. If you've ever tried to troubleshoot a nonworking remote, you know it's frustrating that you can't see if the remote is "lighting up". Although it's difficult to convince a mosquito to tell you if your remote is working, it is possible to convince your cell phone, or any other digital camera, to do so.

Simply look at the infrared emitter at the business end of your remote through the view-screen of your favorite digital camera (or phone). If the remote is working, you'll see the light it's giving off very clearly. It works well and is much easier than training mosquitoes!

I was trying to figure whether a television remote-control was working. You provided a solution. Thank you.

and here i thought...

...they were attracted to CO2. I guess all the makers of the CO2 mosquito traps are worthless and we should just set up heaters.

My understanding is that long distance they track CO2, short distance they use IR.

When will Linux Journal

When will Linux Journal finally kill the post adds that appear on every article with comments?

I knew those suckers had some hidden skills

infrared sucking abilities, sooo not right for us... humans :)

Thermal imaging infra-red

Anonymous's picture

Thermal imaging infra-red (long wave IR) and remote control (near infra-red) infra-red are of different bands. CMOS sensors in cameras are capable of picking up those from remote controls but not thermal images. Even so, many cameras now also include a IR-cut filter before their CMOS sensor, thus.. it might not work. The same applies for mosquitos, I don't think their sensors can pick up NIR.

Cheers

Just a side note on IR

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
