The ultrasonic sensors

February 17th, 2012 by Robot Technology | No Comments | Filed in Sensors

Ultrasonic sensorsUltrasonic sensors, also called ultrasonic rangefinders, are among the sensors to measure distances without contact. These sensors are particularly complementary infrared sensors, since, unlike them, they can monitor a wide conical. They are relatively well represented in the robotics community because of their good price / efficiency ratio. So, there are an increasing number of suppliers, with various models for various uses.

Ultrasonic Distance Sensor With the MSP430

This is the application report from Texas Instruments about distance measurement using ultrasonic and MSP430 microcontroller. The report is provided in PDF file, you may download the application report at the end of this post.

This application report describes a distance-measuring system determined by ultrasonic sound using the MSP430F413 ultralow-power microcontroller. The system transmits a burst of ultrasonic sound waves towards the subject point and after that receives the corresponding echo.

Circuit Connection of Arduino Tutorial Piezo element to detect vibration

Arduino Tutorial: Use a Piezo Element to Detect Vibration. This tutorial shows you how to use a Piezo element to detect vibration, in this case, a knock on a door, table, or other solid surface.

A piezo is an electronic device that generates a voltage when it’s physically deformed by a vibration, sound wave, or mechanical strain. Similarly, when you put a voltage across a piezo, it vibrates and creates a tone. Piezos can be used both to play tones and to detect tones.

Voice generator scheme

Robotic voice generator does not need the variety of complex chips. You can assemble using only ISD2500 ChipCorder® family and few components.The family of chip-coders ISD2500 firm Winbond contains almost everything you need to record and play back voice messages. As chips have mic preamps with AGC, working with the cheapest electret microphones, the output amplifier that runs on the speaker, memory, oscillator, ADC and DAC.
