TFmini-s Micro LiDAR Module 0.1-12M LiDAR Range Finder Sensor Obstacle Avoidance Sensor Tiny Module Single Point UART I2C IO Compatible with Pixhawk Arduino and Raspberry Pi

The TFmini-S has proven to be a solid performer in my recent project. One of its standout features is its fast detection speed, it responds almost instantly, which is crucial for applications involving real time obstacle avoidance or distance measurement. The accuracy is also quite impressive for a compact lidar unit, delivering consistent and reliable readings. What surprised me most is its ability to detect objects at a fairly long range for its size. It handles distance measurement up to 12 meters with good stability, which opens up a lot of possibilities for both indoor and outdoor use(not waterproof). The only downside is the price. While it offers great performance, it’s definitely on the higher end compared to some other distance sensors. That said, if precision and responsiveness are priorities, the TFmini-S is well worth considering despite the cost.

I used this as a help to park my car in the garage. This accurately and quickly responds to the distance of the car.

item is just what i needed. works as described. I love that it comes with two connection options. Used it for a Park Assist LED project

HCSR04 are great for little toys and close up distances. They're cheap so when one breaks, you just replace it. With LTMini not so much. The price-point is such, that if this doesn't work you will want your money back. HOWEVER, you get a device that is much faster and very precise. It's very VERY easy to use - the libraries come standard with Arduino but it's just a serial interface, easily done on every platform - the available library is using SoftwareSerial so if you're using newer devices like the Nano33 you'll have to do a bit of coding yourself. That said, you get very precise data as long as you're further away than 30cm - for my purposes that's perfectly fine. The device made my code simpler too as I can query the unit much more frequent than the cheap HCSR04. Using 5v seems to make the unit hot after some use. I'll run more tests but if passive cooling cannot keep it "functional" I will have a situation where it goes back. I sure hope that won't be needed as I like how effective the device is.

I think it's the best performing sensor to detect approaching targets. I've used it with an Arduino to gauge distance of people approaching to turn on an LED, and compared to the HC-SR04 ultrasonic sensor or a PIR motion sensor, I think it works better. The arduino code referenced in the item description on github works great, because it not only gives a readout of the distance of an object, it gives the strength, which lets you determine whether it's just a small animal passing by or a more substantial object (like a human)

Just got this equipment. Compitable with arduino Small and light weight. Works best in short range below 5 meter. Easy to connect. Recommended for educational projects for high school and college students

It works great, though it appears to be a little cheap. I use it to build a laser scanner based on arduino. I'm prretty happy with it since it's sooo inexpensive. It is only 40 dollars, while Lidar Lite v3 is 150+ and other lidar is 400+ or even 1000+. Of course it's not as precise as those expensive lidar, but it is really cost efficient.

I was able to get this up and running in no time. It appears to be very accurate and a better sensor than the acoustic distance sensor I tried. I wrote come C code to read the data and all is good.
