Description The latest Sensor Shield V5 Expansion Board For Arduino is produced by ALS Robot. This Sensor Shield expansion board to retain the advantages of version V4.0 on the basis of stack design, PCB Immersion Gold processing technology. Newly added many kinds of interfaces, for example, IIC interface, 32 channels servo motor interface, Bluetooth communication module interface, SD Card communication module interface, and so on, more convenient. Sensor Shield allows you to connect to various modules like- sensors, servos, relays, buttons, potentiometers, and many more directly to your Arduino through this Sensor Shield. You can easily connect with usual analog sensors by using this expansion board, such as ray sensor. If you support by this expansion board and the corresponding circuit module, you only need to combine Arduino and sensors module by using special cables, because concrete circuit details achieve by the corresponding sensors module, so you only need to consider that how to read data coming from the sensor by the program in Arduino. Datasheet available here.
