Pour être honnête depuis que j'ai douze ans, je rêve d'avoir un objet (une montre à l'époque) avec tout un tas de capteurs. Et voilà que vingt ans plus tard mon rêve est exaucé avec les smartphones Android. C'est donc avec plaisir que je vais essayer d'expliquer comment les utiliser.
Les capteurs Android.

Parallax's PING))) ultrasonic sensor provides a very low-cost and easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired. You will definitely appreciate the activity status LED and the economic use of just 1 I/O pin. The PING))) sensor measures distance using sonar; an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return.

• Includes the most popular sensors • Angle and G-force sensors • Compass navigation • RoHS Compliant The Parallax Sensor Sampler Kit is a sensor sampler kit that was put together to allow for the most versatile use of different sensors. The kit includes the most popular sensors that Parallax offers including the PING))), PIR, and the multi-axis sensors. This kit can be used together or independently to create an elaborate project.
The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load. Dual output modes and a sensible design that performs within stated datasheet specifications are a few reasons over 100,000 units are in use around the world. NOTE: The product information found on this page currently pertains to Revision B of this product, which provides many updates and features from Revision A. Some of these include:
