These temperature sensors work great with any microcontroller using any single digital pin. We can also connect multiple ones to the same pin. Each one has a unique 64 bits ID burn. It is useable with 3 to 5 volts systems. There is one downside of this sensor is they use the Dallas 1-wire protocol, and which is somewhat complex. This protocol requires a bunch of code to parse out the communication. When you are using this temperature sensor with a microcontroller put a 4.7K resistor to the sensing pin.

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.
