The digital EV3 Ultrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects. It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program.
Students could design a traffic-monitoring system and measure distances between vehicles, for instance. There is an opportunity to discover how the technology is used in everyday items like automatic doors, cars and manufacturing systems.
• Measures distances between one and 250 cm (one to 100 in.)• Accurate to +/- 1 cm (+/- .394 in.)• Front illumination is constant while emitting and blinks while listening• Returns true if other ultrasonic sound is recognized• Auto-ID is built into the EV3 software
The analog EV3 Touch Sensor is a simple but exceptionally precise tool that detects when its front button is pressed or released and is able to count single and multiple presses. Students can build start/stop control systems, create maze-solving robots and uncover the technology’s use in devices such as digital musical instruments, computer keyboards and kitchen appliances.
• Cross-axle hole on button• Auto-ID is built into the EV3 software
The digital EV3 Colour Sensor distinguishes between eight different colours.
It also serves as a light sensor by detecting light intensities. Students can build colour sorting and line-following robots, experiment with light reflection of different colours, and gain experience with a technology that is widely used in industries like recycling, agriculture and packaging.
• Measures reflected red light and ambient light, from darkness to very bright sunlight• Capable of detecting eight colours.It can tell the difference between colour or black and white, or between blue, green, yellow, red, white and brown• Sample rate of 1 kHz• Auto-ID is built into the EV3 software
With this adapter the new Lego Mindstorms EV3 sensors can be connected to the intelligent Lego Mindstorms NXT stone or the Arduino board. This adapter is a UAR converter.
For NXT, works with BricxCC and later EV3 IDE for NXT
Apply with Arduino, NXShield or I2C access point board
Lightweight and small design that fits linearly to the sensors and module
Provides UART with I2C interface
