Me USB Host is an adapter for USB devices. You can use it to connect a Makeblock mainboard to a USB device, such as a USB joystick, a mouse, or a thumb drive. So you can control your robot with your own joystick or something else.
The Makeblock Me Temperature and Humidity Sensor contains a calibrated digital signal output. It adopts specific digital module collecting technology and temperature-humidity sensing technology to ensure high reliability and excellent long-term stability. This Makeblock sensor can measure the temperature from 0? to 50?. Users can use it to build a cost-effective temperature and humidity monitoring system. Its yellow ID means that it has a single-digital port and needs to be connected to the port with yellow ID on Makeblock Orion.
The Makeblock Me temperature sensor consisting of a waterproof probe and long wire is perfect for immersive temperature detection or use for detecting a temperature at a distance.
The Studica Robotics Cobra Line Follower Array provides 4 X QRE1113 IR reflectance sensor mounted on a 9mm pitch. Each sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate.
