Laser vs Ultrasonic - TOF10120 vs. HC-SR04

It's the Battle of the Distance Sensors with the tiny TOF10120 Laser versus everyone's favorite HC-SR04 Ultrasonic. I'll compare the two sensors and test their accuracy on the DroneBot Workshop Distance Sensor Testbed! Accompanying article at https://dronebotworkshop.com/laser-vs...

So I decided to put them both to the test. In fact, I even built a custom testbed to do the job! The TOF10120 is a very tiny sensor that uses VCSEL (Vertical-Cavity Surface-Emitting Laser) technology to measure distance. It communicates using I2C and also has a serial connection. It is available from many vendors, including Amazon and eBay. The HC-SR04 is an ultrasonic sensor that I’ve used many times before, I even did a video and article about it a couple of years ago. It uses pulses of ultrasonic sound and measures the time it takes for them to be reflected back from a target. You then use the speed of sound to determine the distance to the target. I helped out my HC-SR04 by adding a DHT-22 temperature and humidity sensor, as the speed of sound is affected by both variables. After testing out both sensors I put them on my testbed, constructed from the finest quality scrap wood. Nothing is too good for you folks! The results were a bit surprising in some senses, although I was limited by the confines of my workshop and that proved to be a problem with the ultrasonic sensor.
