Sensors
& Measurement
Last update:
14/7/10
Sensors are
a basic component of a mechatronics system, where a mechanical
process is controlled. They are also a crucial part of most
Measurement devices like thermometers
and barometers, however some devices like frequency
meters don't need more than a wire to pick up electrical
signals.
Sensors can be coupled in many ways to build the required
Measurement device like the contact
less tachometer which is built using a proximity
sensor and a modified frequency meter alogarithm.. |

SCANALOGIC-2
PRO: Logic Analyzer and Signal Generator!
This is the ultimate LAB tool in a pocket size package.
SCANALOGIC-2 gives you 20MSPS, I2C, SPI and UART decoding,
FFT analysis, PWM and FM generators, Serial data and bit
stream generators and mixed mode operation allowing you
to generate data on 2 channels while capturing the response
on the 2 other channels... |

IKA-TACH:
Our new contact less tachometer project
This new contact less tachometer project is based on an
ATMEGA48 AVR micro controller, and is able to measure
very high RPMs, as well as very low ones. It is based
on an IR (Infra Red) opto-couple to detect shaft rotation.
It is designed to allow many modifications to me made
buy the users like adding additional sensors...

SCANALOGIC:
ikalogic's easy to build high performance logic analyzer
Here is one project we are really proud of, and we hope
that it's simple design will encourage you to build your
own, and use the provided software to obtain your own
logic analyzer for less than 10$. This device can help
you in most of your projects, it's an essential measuring
device when it comes to digital electronics. |

Infra-Red
Proximity sensors (PART 1)
Based on a simple basic Idea, this proximity sensor, is
easy to build, easy to calibrate and still, it provides
a detection range of 35 cm (range can change depending
on the ambient light intensity). For simplicity, this
sensor doesn't provide ambient light immunity, but the
Next article (PART 2) treats this problem. |

Infra-Red
Proximity sensors (PART 2)
This article deals with a more advanced IR proximity sensing
scheme, it is also more expensive but provides more accurate
results even in sunny outdoor environment.
This sensor is practically not affected by ambient light,
and it can provide detections ranges that exceed 1 meter. |

99
000 RPM Contact-Less Digital Tachometer
This article describes how to build a contact -less tachometer
(device used to count the revolutions per minute of a
rotating shaft) using a 8051 microcontroller and a proximity
sensor.

Build
a 40Mhz Frequency meter
This article shows how to build a small, cheap and simple
frequency meter, without any fancy, out of reach components.
The simple proposed design can measure frequencies up
to 40 Mhz with errors below 1%!. Based on an ATMEGA16
microcontroller. |

Build
a 500 KHz Frequency meter
Based on the famous AT89S52 microcontroller, this 500
Khz frequency-Meter will be enough to trace and debug
simple circuits, to adjust 555 timers frequency and perform
all kind of frequency measurements in Digital circuits. |

build
a digital thermometer (DIY)
This article shows you how to build a digital thermometer
from the beginning to the end, using a thermistor and
a 8051 microcontroller. Being based on our tutorial about
Analog to Digital conversion,
it is very easy to understand the functioning of the device,
and you can build it with any microcontroller even if
it doesn't have a built in ADC. |

Electronic
Sensor Circuits & Project, Forrest M., III
Mims
This is a reference that covers all the aspects of sensors
and their applications. I didn't buy this books, but it
speaks for itself on the internet; a lot readers reviewed
this book on amazon website, and they all find it amazingly
interesting, full of example projects, and fairly simple
to understand and implement into your projects. |

Electronic
Sensor LAB. (Educational KIT)
I remember how happy I was, years ago, when I bought this
kit from RadioShake! It Has all what you need to get you
started in electronics. With a set of sensors (motion,
temperature, touch, pressure, magnetic, sound, light..)
and all the needed equipment (batteries, wires, breadboard,
ICs, potentiometers, etc..), you can start to assemble
simple projects, available in the book that is shipped
with the kit. **I RECOMENT
THIS KIT TO ALL BEGINNERS** |
