#cplusplus#hap#mid_360#ros#ros2 Livox ROS Driver 2 connects your Livox LiDARs like HAP and Mid360 to ROS (Noetic) or ROS2 (Foxy/Humble/Jazzy) on matching Ubuntu versions. Clone the repo in a workspace/src folder, build Livox-SDK2, then run ./build.sh with your ROS version, and launch with roslaunch or ros2 launch files from launch_ROS1/ROS2 folders—edit JSON configs for IP, ports, frequency (up to 100Hz), and formats. This lets you quickly test and visualize point clouds in RViz for robotics development, saving time on setup and debugging. https://github.com/Livox-SDK/livox_ros_driver2

The temperature -40 °C is the same as -40 °F. This is the only temperature where Celsius and Fahrenheit match exactly. 🌡️❄️ @googlefactss #Temperature#Celsius#Fahrenheit#Science#Facts

Crickets can be used to estimate temperature using Dolbear’s Law. The snowy tree cricket is the best species for this method because its chirp rate closely matches temperature changes. 🦗 Count chirps in 14 seconds and add 40 to estimate the temperature in °F. Crickets chirp faster in warm weather and slower in cold because they are cold-blooded. 🌡️ To estimate temperature in °C, count chirps in 8 seconds and add 5. This method is fairly accurate between 5 and 30°C. 🌡️ To convert °F to °C, subtract 32 and multiply by 0.56. 🥵🥶🦗🌡️ [Read more] @googlefactss #Insects#ScienceFacts#Nature#DidYouKnow#celsius#Fahrenheit If you have ideas or feedback contact us: @Googlefactss_Feedback_bot
