TFmini LiDAR(ToF) Laser Range Sensor(12m)

1. Example Code for Arduino-PC Serial Port Debugging

Since TF mini is a serial device and the ordinary Arduino only has one hardware serial port, so we recommend you to use a software serial port to match the sensor. Users can also use multi-serial port devices such as Arduino Leonardo and Arduino Mega2560. Here we choose Arduino UNO as a controller, which is very common to see and define D12 and D13 as software serial port. PC serial port tool is needed. Data been read will be displayed in the serial port tool interface.

2. Example Code for Arduino-LCD Distance Display

In practical application, the sensor will generally work offline. We provide a special case, which powered by a lithium battery and display distance measurement data with LCD. It is especially suitable for outdoor usage.

3. Upper Computer Display

In addition to reading data through a single chip, we can also use PC Software to read distance output. Connect TF Mini LiDAR(ToF) Laser Range Sensor to PC by an USB to TTL converter and read data by upper PC.

4. Example Code for Arduino-Black & White Line Detection

TF Mini laser ranging radar is an optical sensor, but any optical sensor, the sensitivity of the light will be higher. We can use this feature to achieve close-range black and white line detection, line-tracking inspection. (NOTE: black is to absorb all the lights, do not reflect; white is to reflect all the light, do not absorb) We use the signal strength 'Strength' to distinguish between the two colors.
