Various sensors have different operating ranges which should be considered while working with it else the sensor may get damaged permanently. In this article I cover an analogue sound sensor with LEDs displaying for the loudness (noise level) of the sound detected. Each LED is checked in turn with a hundredth of a second delay between each check. After all have been checked and illuminated if necessary, all are turned off in the opposite order to give a rise and fall effect. The port of Me Sound Sensor has three pins, and their functions are as follows: Wiring mode Connecting with RJ25 Since the port of Me Sound Sensor has black ID, you need to connect the port with black ID on Makeblock Orion when using RJ25 port. Examples: LEGO sound sensor; microphones in phones, computers, karaoke machines, etc. http://en.wikipedia.org/wiki/Sensors, List of sensors: http://en.wikipedia.org/wiki/List_of_sensors, The Ear, Neuroscience for Kids: http://faculty.washington.edu/chudler/bigear.html, How Hearing Works (3:08-minute video), Med-EL Kid's Corner: http://www.medel.com/us/How-Hearing-Works, Hearing Direction and Distance by Ron Kurtis: http://www.school-for-champions.com/senses/hearing_direction.htm#.Uu2duvldUnE, How Your Ears Work, Kid's Health, Women's and Children's Health Network: http://www.cyh.com/HealthTopics/HealthTopicDetailsKids.aspx?p=335&np=152&id=1463.

The XL-MaxSonar and LV-MaxSonar sensors assume an air temperature of 22.5 degrees Celsius. In multicellular organisms, the body is a system of multiple interacting subsystems. There are also three integer variables that will get their values during setup but are declared here so they are available for the loop too. soundSample = analogRead(soundPin); units and these again are bundled into subject areas. 5), Knowledge gained from other fields of study has a direct effect on the development of technological products and systems. Burglar alarm systems; Leak detection system; Moisture / Humidity Sensor. A vector sensor is an underwater listening device used to detect sounds in water and convert acoustic energy into electrical energy. Sensors •1) Active sensors: Require an external source of power (excitation voltage) that provides the majority of the output power of the signal •2) Passive sensors: The output power is almost entirely provided by the measured signal without an excitation voltage Sound Sensor Mini-Activity: Observe student pairs as they experiment with the LEGO sound sensor during the mini-activity described on slide 14. The signals are then processed in the brain, resulting in immediate behaviors or memories.
