The new MEGA Sensor Shield V1.0 dedicated sensor expansion board for Aduino, it is designed to gather the advantages of various expansion boards. It uses Immersion Gold PCB processing technology. specially designed Bluetooth module communication interface, SD card module communication interface, APC220 radio frequency module communication interface, and RB URF v1.1 ultrasonic sensor interface, more easy to easy to use. For aduino beginners, the circuit simplifies this sensor expansion board in the true sense, can easily be used to connect the sensor. This sensor requires only a general 3P sensor cable (Regardless of a digital connection and Simulation of connecting line), complete the circuit connection, Preparation of the corresponding program, download it to MEGA controller, the read sensor data, or receive wireless module data return ,after operation processing, and ultimately easy to complete your own interactive works.
