Shooting Laser To Measure Distance MP3 Free Download

Can measure in 0.1 mm range??

OK, let fined springs can do the job

Is it possible to use laser sensor to measure the water level?

i want to use it for people counting in a room. i need direction for + and - for counting

My company did a project using one of these TimeOfLight sensors, and I worked with them extensively. I did not use the Adafruit drivers, I dealt with them directly with I2C commands to the registers. I detected a problem with them, they are not supposed to be sensitive to temperature or ambient light, but I found them to have a small susceptibility to both, It was enough to give us problems. Since the modules attempt to compensate to temperature changes, sometimes they over-compensate, sometimes they under-compensate, there was no way of telling which way any given sensor would go. Also, sometimes they would become more stable in their readings with a given temperature change, sometimes they would become more erratic. I decided I needed to create a test fixture to try to characterize these things. I built up a breadboard PCBA with ten of these devices. I used one IO pin from the Arduino to drive the reset pin of each device. I would release one devise from reset at a time and assign it a new I2C address, and in this way I was able to work with all ten devices at once. I put that PCBA in a wooden box with a lizard-warming heat source. The Arduino had a temperature sensor and a relay to power that warmer. It could be queried from a PC to give the current distance reading from any device, to report the temperature, and to turn the heater on and off. The PC would have the box heat to a configurable temperature, keep it there for some hours, and then let the box cool to ambient for some hours, taking and recording the time and temperature and device readings every few seconds. All the data went to a .csv file that I could pull up in Excel and then plot the data. I noticed behavior changes at 8:00am and decided it was because people were coming to work, lights were turning on, and the box lid that the devices were reading to was translucent wood. Aluminum foil tape fixed that problem. We were able to fully understand these distance sensors and figure out how to make them work for out project. We had no further troubles with these sensors.

can it measure with 3 digits accuracy, for example 40.231 cm; 50.446 cm; 21.273 cm, etc ?. And what is maximum range ? . I want to measure distance between 2 cm to 300 cm

this sensor is similar to ultrasonic sensor??

Do you think it's possible to use this device to actually focus a laser instead of a image like a lrad military laser defense system

You cannot use that on sunlight ,I tried it and it is blind but perfect inside
