SainSmart 20 Sensor Modules + UNO R3 Education Starter Kit with 1 Relay Module + HC-SR04 Distance Sensor is an Arduino-compatible kit suitable to develop applications of many types, including those for the Internet of Things. |
The kit has more than 16 projects for the beginners. This is the new SainSmart Sensor Starter Kit, developed specially for those beginners who are interested in Arduino. You will have a complete set of Arduino's most common and useful electronic components. What's more, we will offer you a detailed PDF tutorials including project introduction and their source code. You may learn about Arduino through using these basic projects. This kit will help you control the physical world with sensors.
The SainSmart Uno R3 now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory. The ability to have the Uno show up as a keyboard, mouse, joystick, etc. 3.3VV/5V Supply Voltage and IO Voltage is optional. More 3.3V modules supported, such as Xbee module, Bluetooth module, RF module, GPRS module, GPS module, LCD5110 Backlight and so on, but the original version can only support 5V IO. Add SDA and SCL pins next to the AREF.
About the HC-SR04, there are 4 pins out of the module: VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. We can calculated the distance easily: Distance = ((Duration of high level)*(Sonic:340m/s))/2
