Robotic environmental sensors are robotic devices used to detect environmental factors such as temperature, precipitation, and humidity. They are typically used to study climate change, monitor drought, and observe storms. Some robotic sensors may take autonomous measurements, while others may be controlled by a human operator. Often, robotic sensors send data to a central computer terminal, which is then analyzed and used to create charts, graphs, and maps. Robotic environmental sensors are becoming increasingly popular due to their accuracy and efficiency in measuring environmental conditions.
