Advanced color accuracy solution for all of your laptop and desktop displays - See, share and print your images just as you intended with confidence. Fast and easy, full calibration takes only about five minutes to ensure color accuracy.

Room light monitoring determines optimal monitor brightness so you see fine shadow detail and highlights in your photos, ensuring your edited images match your prints.

“Before and After” evaluation of your calibration results using your own photographs, to focus on details that are important to you.

use: 1. +5 +5 is the positive input port of the power supply, which can be connected to a voltage of 3.3V~5V

2. GND GND is the negative input port of the power supply. OUT OUT is the signal output port, which is connected to the I/O port of the single-chip microcomputer. Generally, it is connected to an external interrupt.

For other main control boards or higher-level main control boards (such as Arm), if you need to set the I/O port to input/output mode, you must set it to input mode/receive mode, otherwise it cannot be used. 51 series MCU can be used directly, no need to set input and output mode

480 VAC input voltage for multiple uses

Polypropylene housing, UV stabilized for durability

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so you can detect it. Black & dark colored stuff will absorb the IR light so that it isn't detected. Likewise, if something isn't in the way of the sensor, it won't trigger either.

These sensors are handy when you want to detect if something has passed by the sensor, or a very simple hand-detector. Also sometimes these are used as rotary encoder, if the encoder wheel has black and white stripes, the photo sensor is fast enough to tell you the RPM. Most common usage of these sensors is for line following robots, they're so small and easy to solder, you can pack them together very close.

This sensor is compact, breadboard friendly and easy to solder to. It even has handy markings on the plastic so you know which side is the LED and which side is the phototransistor output. We don't include any 470Ω -1KΩ resistors for the Infrared LED, or a 10KΩ for the output pullup. But you do get a pack of 5!
