5 Channel TCRT5000 IR Array Tracking Sensor Module is a sensor board designed for use with line follower robots. This IR sensor module has been sufficient to meet the frequent task of tracking, but also with the infrared distance sensor and touch detection sensor. This TCR T5000 array unique makes your robot design able to adapt to the situation easily. It is specifically designed as a black line especially suitable for the complex of the black and white line, cross black and white line detection. This high-quality sensor module has 6 roads high sensitivity infrared sensor (5 escapes patrol, 1 road), to the recognition of black and white line accurately.

The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in tilt sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
