If you’ve ever had to move around in a dark room before, you know how frustrating it can be. This is especially true if you are in an unfamiliar place. [Brian] has attempted to help solve this problem by building a vibrating distance sensor that is intuitive to use.

The main circuit is rather simple. An Arduino is hooked up to both an ultrasonic distance sensor and a vibrating motor. The distance sensor uses sound to determine the distance of an object by calculating how long it takes for an emitted sound to return to the sensor. The sensor uses sounds that are above the range of human hearing, so no one in the vicinity will hear it. The Arduino then vibrates a motor quickly if the object is very close, or slowly if it is far away. The whole circuit is powered by a 9V battery.

The real trick to this project is that the entire thing is housed inside of an old flashlight. [Brian] used OpenSCAD to design a custom plastic mount. This mount replaces the flashlight lens and allows the ultrasonic sensor to be secured to the front of the flashlight. The flashlight housing makes the device very intuitive to use. You simply point the flashlight in front of you and press the button. Instead of shining a bright light, the flashlight vibrates to let you know if the way ahead is clear. This way the user can more easily navigate around in the dark without the risk of being seen or waking up people in the area.

This reminds us of project Tacit, which used two of these ultrasonic sensors mounted on a fingerless glove.

How to use MQ2 Gas Sensor – Arduino Tutorial

FISYBZAIB2BSPGJ.MEDIUM

by codebender_cc @ instructables.com:

The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino.

The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane ,alcohol, hydrogen and smoke.

Some modules have a built-in variable resistor to adjust the sensitivity of the sensor.

An introduction to sensors

arduino, PyroEDU, Sensor Commenti disabilitati su An introduction to sensors 

Sensors Experiments

PyroEDU began in 2012 with the mission of offering free online courses teaching the fundamentals of electrical engineering in an approachable and entertaining manner. Rather than studying textbooks and advanced mathematics, students are taught using a learn-by-doing approach that follows four basic steps: introduce the topic, explain the theory, build an experiment to demonstrate the theory, and offer real-world examples to demonstrate how the topic is utilized today. Students can interact with other students and the instructor via the PyroEDU forums or by joining one of PyroEDU’s hosted classrooms on uReddit or P2PU.

PyroEDU is currently teaching its sixth course, An Introduction to Sensors, covering a wide variety of sensors from motion detectors to temperature sensors. This sixth course is the capstone in the Introductory Series of courses PyroEDU offers (visit http://www.pyroelectro.com/edu/ for a complete listing of courses in the Introductory Series). Working with The Gadgetory, an online electronics retailer, PyroEDU will be offering a comprehensive kit that includes all the parts necessary to complete the Introductory Series of courses. More advanced series are planned in the future which may include courses in animatronics and robotics.

UDOO_NEO

Wireless, Credit-Card sized, Android + Linux + Arduino™, Embedded Sensors, starting from $49. What else?

UDOO Neo embodies a new concept: a single board computer suitable for the Post-PC era:

  • Like a Raspberry Pi, you can program it in any language and run a full Linux environment with graphic interfaces.
  • You get all the simplicity of an Arduino-compatible board, thanks to the Cortex-M4 and the Arduino UNO pinout layout, with the possibility of adding most Arduino™ shields, actuators and sensors, both analog and digital.
  • An incredible, smoothly-running Android 4.4.3, it gives you the possibility to build new Android-based smart devices.
  • You get a wireless module: Wi-Fi 802.11 b/g/n + BT 4.0 (Classic Bluetooth and Bluetooth Low Energy), because we hate cables.
  • 9-axis motion sensors are embedded, to build your perfect drone/robot/3D printers/whatever or create new kinds of interactions with the real world.
  • Open-source hardware: because we love to let you hack things or create new devices from scratch!
  • Starting from $49!

by Mahesh Venkitachalam:

I was in Bhutan last December, and as we travelled to different locations, I kept wondering what the temperature and altitude was, and wished I had some gizmo that would show me these values. Back home, I did a bit of research on altitude sensors, and one that came up was the cheap BMP180 sensor. It measures temperature and pressure, and the latter can be used to calculate the altitude. It’s been lying around with me the past few months, and now I’ve finally gotten around to building a display around it.

HDC1000 temperature and humidity sensor breakout, with Arduino library!

DSC_5869-1024x784

by Francesco Truzzi :

Some time ago I came across a new chip from TI, the HDC1000. It’s a temperature and humidity sensor with I2C interface and requires little to no additional components. It comes in an 8BGA package: we can all agree it’s pretty small.
Some of the peculiar characteristics of this chip are that it has a DRDYn pin which goes low any time there is a new reading from the chip (so you can precisely time your requests) and that the sensor is located on the bottom of the IC, so that it’s not exposed to dust and other agents that may false the readings. Also, it has an integrated heater that can remove humidity from the sensor.

So I developed a very small breakout board for this chip as well as an Arduino library (yay, my first one! raspberryPi and nodemcu might come next).
