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.

Quarton Laser Module VLM-650-03 LPA (ECONOMICAL DOT Laser)

Baluue 10pcs Vibration Sensor Module Normally Closed Alarm Switch Module High Sensitive Efficient Vibration Switch Module for Car Truck Auto Vehicle

• TCRT5000 infrared emitting diode constantly launch infrared sensor, the infrared ray is emitted when reflected back were not reflected or but strength is not big enough, the infrared receiving tube has been in the off state, the output end of the module at this time as the low level, indicating diode has been put out state.
• Tested objects appear within the scope of testing, infrared light is reflected back and strength is enough big, infrared receiving tube saturation, at this time the output of the module for the high level, indicating diode lit up..
