The TF Luna LiDAR is a compact Time-of-Flight (ToF) sensor designed for distance measurement and obstacle detection. Utilizing LiDAR technology, it emits laser pulses and measures the time it takes for the reflected signal to return, calculating the distance to an object. This sensor is widely used in robotics, drones, and various automation applications where precise distance measurement is crucial.
This circuit is designed to measure distances using two TF LUNA LIDAR sensors, which are interfaced with an Arduino UNO microcontroller via I2C communication. The Arduino is programmed to read distance measurements from the LIDAR sensors and output the data serially. The entire system is powered by a 5V battery, ensuring portability and ease of use.

This circuit features an ESP32 CAM module interfaced with a TF LUNA LIDAR sensor for distance measurement. The ESP32 CAM provides power to the LIDAR sensor and facilitates communication via its RX and TX GPIOs. A Polymer Lithium Ion Battery powers the circuit through a Step Up Boost Converter that elevates the voltage to the required levels for the ESP32 CAM and LIDAR sensor.

Q: Can the TF Luna LiDAR sensor be used outdoors? A: Yes, but direct sunlight may affect the accuracy of the sensor. It's best used in shaded or indoor environments.
Q: Is the TF Luna LiDAR sensor waterproof? A: No, the TF Luna is not waterproof and should be protected from moisture and water damage.
Q: What is the maximum baud rate for UART communication? A: The TF Luna supports a baud rate of up to 115200 bps for UART communication.
Q: How can I change the communication interface from UART to I2C? A: The TF Luna can be configured to use I2C by connecting the SCL and SDA pins and using the appropriate library or code to communicate via the I2C protocol.
