Buy 3Pcs Keyes Brick Grayscale Sensor(Pad hole) Anti-reverse Plug White Terminal TCRT5000 Sensor Module good price
Description:
1. This is a commonly used Grayscale Sensor that uses a TCRT5000 reflective black and white line to identify sensor components. The principle of the sensor is to use the different reflectivity of infrared to color and convert the strength of the reflected signal into a current signal. When the sensor does not detect an object or detects a black object, the signal terminal is at a high level; when a white object is detected, the signal terminal is at a low level; its detection height is 0-3 cm. We can adjust the sensitivity by rotating the potentiometer on the sensor, that is, adjusting the detection height. Sensitivity is best when the potentiometer is rotated, which is the critical point between the D1 LED and the D1 LED.
2. The sensor is compatible with various microcontroller control boards, such as the microcontrollers. When using it, we provide a method for using this sensor with the microcontrollers.
3. The sensor comes with a 2.54mm anti-reverse plug white terminal. When in use, we can connect to the MCU with DuPont cable. To facilitate wiring, we specially designed an expansion board that is fully compatible with this sensor and the UNO R3 microcontroller. We only need to stack the expansion board to the UNO R3 MCU, and use a 3P double-head XH2.54 plug wire (anti-reverse) to connect to the expansion board, which is simple and convenient.
4. At the same time, the sensor comes with 4 3mm diameter positioning holes, which allows you to fix the sensor to other devices.
I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
