      Description

      This product is based on ToF (Time of Flight) principle and integrated with unique optical and electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance detection.


      ToF is the abbreviation of Time of Flight technology, and its operating principle is as follows: a modulated near-infrared light is sent from the sensor and reflected by an object; the distance to the object to be shot can be converted with the sensor by calculating the time difference or phase difference between the light sending and the light reflection, so as to produce the depth information. 


      Applications:

      • Drone altitude holding and terrain following

      • Machine control and safety sensor

      • Robot distance detection


      If you are using Seeeduino Lite then just put it straight into the Grove Serial Interfaces.

      Hi,I did the same question for the Grove - Ultrasonic Ranger - SKU 101020010.Basically, I need to perform some initial distance tests (reliability, accuracy, limits under different weather and field conditions involving humidity, dust and fumes) for a project that was recently approved, and select any of these technologies to be implemented (ultrasound or lidar).The issue is that the buying process has several stages and it could take months to even make an order and I need to start ASAP.

      Hi there~ We've got your point. However here is the process-- you need to send the email to the ### order@seeed.cc ### for sample application. So, could you please copy your last reply to our email. Sorry for the inconvenience. Regards

      Is it possible to connect the device to a Wemos Mini D1?

      Hi there~ We do not have Wemos on our hand,so not for sure. Since the wemos mini D1 support Arduino, is highly likely can work with TF Mini LiDAR.

      I've given up trying to connect to a wemos mini di. Had no success. Now i'm trying with a nodemcu and having similar problems. Are you able to help configuring it? I keep modifying this line in the code without success :SoftwareSerial serial1(16,5);Are you able to help with pins to attach to?

      HI there~One more question,did those boards you use have two hardware UART, because the baud rate is 115200,and the software UART can not support it.So please make sure the boards have two hardware UART.regards

      I'm trying to detect the object under 30cm (about 10~20cm). Not for the exact distance between the sensor and the object, just if the object was existed or not. Can we detect the object?

      Hi there~ You mean 10~20 away from the sensor,right? Could you please tell me what is the size of this object? Regards

      Yes, 10~20cm away from the sensor. And the size of the object is about 3cm (just the bar.. a rectangular parallelepiped)

      Hi~Unfortunately, the measure range is 30cm--12m, it can not get an accurate date within 30cm.Regards

      According to the pin mappings there are two at D10 and D9, and another at D7 and D8 but i'm struggling with what values to put into SoftwareSerial serial1(x,y). Can you suggest values?

      Can you please share the refresh rate of the depth points reported (like 30Hz or 30 points per second) for this sensor? I couldn't find it in the datasheet. thanks!

      Hello SeeedStudio, This item had been running about a week until it decided not to respond. Given my code which worked firt, my serial monitor keeps writing "initializing...". At best, I can only obtain "Dist:65335 SigStr65335" "header not found". Sadly enough, every thing was perfectly working before, with the same arduino code. How can I solve this issue ? Thanks Lawrence
