ESP8266 DS18B20 temperature sensor, Arduino IDE, EasyIoT Cloud

In this tutorial we will show how to build WiFi ESP8266 DS18B20 temperature logger connected to EasyIoT Cloud. All material costs less than 5$ on ebay. EasyIoT Cloud works also on mobile phone or tablet. Native Android app is also available. Also see simplified sensor version (Plug and Play): http://www.instructables.com/id/ESP8266-Temperature-Logger-With-Email-Alarm/ Step 1: Materials ESP8266 module […]

Sensing Weight With A Flexiforce + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

Felxiforce is a force sensor that is very similar to FSRs we just wrote about in principal. They change their resistance when you apply force to them. (The flexi part of the name is because they are flexible) Felxiforces are about twice as expensive as their FSR cousins, but these are much more stable, and

Touch Sliders With A Softpot + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

You all know the potentiometer, you turn it, and you can read on your arduino where it was turned to. Well 3M makes a product called the softpot that is a linear touch potentiometer. So instead of turning a knob, you touch it. The really nice thing about these is that they are great for

Can You ID This? ID-20 RFID Reader + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

A few weeks ago we showed you how to control your arduino over serial. Well this week are going to do the same thing. Only this time instead of using the serial monitor to send the commands, we will be using the Innovations ID line RFID reader. RFID, or Radio Frequency Identification, is basically a

Tilt Sensing with the RPI-1031 + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

Once in a while something comes out that I think is going to be really awesome, but when you get it, it is just so so. Im sure you all know what I mean… But yeah… This is one of those. The RPI-1031 available from sparkfun is a pretty simple (heck, it is dead simple)

The Internet of Bees: Adding Sensors to Monitor Hive Health

Electronics News Updates / By Ibrar Ayyub

The Digital Beehive uses Wi-Fi to broadcast a beehive’s weight, humidity, temperature, and battery voltage every minute to SparkFun’s data channel service called Phant. The raw data can be seen here but you can view some prettier graphs of the data here on analog.io (sign-in required). On a visit to Portland, Oregon, last summer my friend

Line Sensing. QRE1113 Reflectance Sensor + Arduino

Blog / By Ibrar Ayyub

The QRE1113 is a common reflectance sensor often used in robotic line followers. The sensor works by shining an IR LED down and seeing how much of that light bounces back using a phototransistor. Because dark colors will bounce back less of the light, the sensor can be used to tell the difference between white

One Wire Digital Temperature. DS18B20 + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

I know… you are probably thinking “Another Thermometer! How many do you need to cover?” – Well… All of them. But really, they all have something different to offer. For instance this guy, the DS18B20, has a unique serial-number sent with it’s data, so if you needed to have 50 of these on one bus,

Proximity Sensing with the VCNL4000 + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

I’m not really sure why, but proximity sensors are some of my favorite things in the sensor world. Maybe because there are so many of them? Who knows. Whatever the reason, the VCNL4000 is another proximity sensor that caught my eye, so I picked one up from Sparkfun on this handy breakout board. The VCNL4000

Sensing Orientation With The ADXL335 + Arduino

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

I know, I know, this one has such a simple name. Where’s the pun? Honestly, the description was just to long to include one. Maybe it could have been “What’s Up? Sensing Orientation With The ADXL335 + Arduino” – Ehhh… Probably not. A few weeks ago we wrote a tutorial about using the ADXL345 to
