[Brian] started out with a clear and concise goal, “allow a regular human to associate an audible tone with a temperature from an infrared contactless thermometer.” With his latest project, the ESPeri.IRBud, he has achieved this goal.
One of our favorite parts of [Brian’s] post is his BOM. Being able to easily see that the IR temperature sensor costs $26 at DigiKey is unbelievably helpful to readers. This specific sensor was chosen because others have successfully interfaced it with the Arduino. Not having to reinvent the wheel is good thing! For the build, [Brian] decided to hook up the IR temperature sensor to a re-purposed flexible iPhone headset wire. Having used headphone sockets to connect to the sensor and speakers, the actual device is quite modular. Hearing this thing in action is quite cool, it almost sounds like old-school GameBoy music! Check it out after the break.
Have you used an IR temperature sensor in one of your projects? Let us know.
NO sound. Even after I turned of the radio, a faint tone at one point.
If using a phone or camcorder use a headphone on the audio out of the experiment and place one pad on the mic of the video device. It don’t take much volume. This is the basis of the old acoustic coupler used on jack-less phones, for dial-up service.
