AITIAO 2Pcs GY-271 QMC5883L Triple Axis Compass Magnetometer Sensor Module 3-5V IIC Electronic Compass Module Magnetic Sensor Module

TCRT5000 infrared reflection sensor, infrared emitting diodes constantly emit infrared rays.
Widely used for pulse data sampling of watt hour meter, paper detection of fax shredder, obstacle detection, black and white line detection.
also it provides a versatile infrared detection system solutions for automation machinery devices.
When object is in detecting range, infrared ray will be reflected back with high intensity, the module outputs high level and indicating diode is on.
when the infrared ray emitted is not reflected back or intensity is not high enough, the infrared receiving tube is in the off state and module outputs low level,while indicating diode is off.
Black line low output, white line high output.
