VL53L0X – measure the distance with a photon reflector

VL53L0X – measure the distance with a photon reflector

Well, I decided to tell you about it – for some reason, these sensors are not as popular as ultrasonic ones. In the sensor housing there is a laser, an array of avalanche LEDs (ultra-fast SPAD Single Photon Avalanche Diodes) and a small controller that manages all these things – and where without it today?

VL53L0X – measure the distance with a photon reflector

What is this?! The principle of operation is as simple as soap – almost like an ultrasonic sensor, only an infrared beam of 940 nm is used. A few years ago, a friend of mine needed to quickly focus his camera. He discovered sensors that were just starting to be produced – VL53L1X: small, economical, accuracy and measured distance (up to 4m) were sufficient for him and asked me to https://tonaton.ug/s_254-manicure-sets deal with them. Over the years, I don’t remember what idea came to my mind, but I ordered this sensor. Another article from https://jiji.ng/central-business-district/12-car-batteries/75ah the "what I found in my trash" series. Bottom side – LDOs and level converters: By the time it came from China, the idea had already been forgotten, and the sensor itself had collapsed somewhere. I ask why not painted?!

The sensors were fresh, there was little information about them, and there https://tonaton.co.ke/s_288-cassava-stems were no ready-made libraries yet. — Photon reflector, comrade general! A few years later, I found on Ali a cheaper version of such a sensor, with a shorter distance. The usual method is to twist the lens and evaluate the image contrast programmatically, it didn’t roll in terms of speed. Over the past time, it has interested arduinists, libraries have appeared, and now it takes only a few minutes to put this sensor into operation. And last week, picking out dust from the corners of the workplace, I dug out this sensor too. Which was done immediately. The top side of the board is the sensor itself: — I myself see that it is a photonic reflector.
