Or maybe you have hay fever and want to know what kind of pollen makes you sneeze in spring? Questions like that prompted me to build a simple device for capturing airborne particles so they can later be examined under a microscope. Before you take your next breath, here is an important piece of advice: DON'T! It turns out that the air is full of pollen, dust, spores, artificial fibers, and some things that definitely do not belong there such as pieces of decomposing vegetation, tiny insect body parts, and moth poop.
(OK, the moth poop bit was an exaggeration; it could have been butterfly poop.) That is the air outdoors. Indoors it gets much worse. If you are still reading, you are either very brave, or something is seriously wrong with you. If you have questions or comments, or if you have found an error on this site, please let me know. Tilt Sensor Tutorial.
What is a tilt sensor? Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. They are usually made by a cavity of some sort (cylindrical is popular, although not always) and a conductive free mass inside, such as a blob of mercury or rolling ball. Tilt switches used to be made exclusively of mercury, but are rarer now since they are recognized as being extremely toxic. While not as precise or flexible as a full accelerometer, tilt switches can detect motion or orientation simply. Basic Stats These stats are for the tilt sensor in the Adafruit shop which is very much like the 107-2006-EV.
Size: Cylindrical, 4mm (0.16") diameter & 12mm (0.45") long. No IC touch sensor for.....whatever you want! Parts: -4 x 2N3906 PNP transistors or similar (note below about transistors) -1 x 1N914 diodes -1 x 10v 1000uF capacitor (keep the voltage below 10v / Caps rated voltage or it will explode!) -1 x Barrel jack -1 x 9v 300ma adapter -1 x 120 Ohm resistor (Brown, red, brown) -1 x Ceramic capacitor -some shield wire (I don't use it because I don't have any but if you do use it!) -some copper clad is nice to have but not needed -ugly perf board -Breadboard/protoboard are handy as well Tools: -solder -soldering iron -tin snips for copper clad and ugly perf board *Note: The transistors I used are random transistors similar to 2N3906 but I live in Canada and can only get a package of transistors "similar" to 2N3906 so protoboards are good to test this out on.
Mine are bi polar and let some electricity through one way all the time wether they are off or turned around let no electricity through when off. FSR Sensor tutorial. Touch 8 - Custom Control Module based on a ATMEL AVR Microcontro. Alberto Ricci Bitti has developed a cool touch controller called the Touch 8. I can see this programmable controller having the ability to replace lots of single purpose controls that are used to control equipment. "Touch8 is a module that integrates a 3" LCD touch-screen and a RISC processor. The processor includes a powerful library to handle graphics and windows. The module also includes a DC power supply and RS485, CAN 2.0B and TTL-serial interfaces to connect to every kind of machinery.
There are also I/O pins including SPI and I2C. Touch8 uses free, open-source, ANSI compliant C compilers and IDE. The additional library for graphics windows comes ready-to-use, and many practical examples of programs ready are posted online. Gas Sensors.
