Infrared/IR

Infrared sensors: IR obstacle and line-tracking modules, TCRT5000, QTR-8RC arrays, Sharp IR distance, IR remote receivers and MLX90614 contactless thermometer.

Sensors that use infrared light: obstacle avoidance modules, TCRT5000 line-following sensors and 5-channel arrays, the QTR-8RC reflectance array, speed and wheel encoder sensors, the Sharp GP2Y0A21 analog distance sensor, KY-005 IR transmitters, KY-022 and 38kHz IR receivers for TV remotes, and the MLX90614 contactless temperature sensor.

Which IR sensor?

For a line-following robot, use TCRT5000 sensors or an array pointed at the floor. For detecting nearby obstacles, an IR obstacle module. To control a project with a TV remote, a 38kHz receiver. For measuring temperature without touching, the MLX90614.
