Using drones for night-time crop protection offers several advantages. The cooler temperatures at night help in effectively targeting nocturnal pests and reducing the risk of pesticide evaporation, making it an ideal time for application. This method is especially popular during the peak season for plant protection, where operators using the P20 plant protection drones that support autonomous flight often choose to work after dark. Night Plant Protection However, working at night can present challenges, particularly with the stability of the drone's flight height. Many operators have reported that the P20 may experience unstable altitude during nighttime operations. So, what causes this issue, and how can it be resolved? Main Cause: During the night, dew formation is common. High humidity leads to the creation of water mist in the air, and dew can accumulate on plant leaves. The terrain module or ultrasonic sensors located on the bottom of the P20 are vulnerable to contamination from this moisture. When the drone takes off or lands, the ultrasonic probe can come into contact with dew on the foliage, which affects its ability to accurately measure altitude. This contamination can lead to unstable flight performance, especially when operating over fields with high humidity or dew accumulation. As a result, the drone might struggle to maintain a consistent height, potentially impacting both the effectiveness of the application and the safety of the operation. Solution: 1. During nighttime operations, it's recommended to regularly inspect the surface of the ultrasonic probe for dew. If any moisture is detected, wipe it clean immediately to ensure accurate readings. 2. If possible, lower the drone’s flying height as much as safely feasible without compromising the effectiveness of the crop protection or the safety of the equipment. Setting the height to 2.1 or 2.2 meters can help reduce the impact of water mist on the ultrasonic signals, improving overall stability during flight. By taking these precautions, operators can significantly improve the performance of their P20 drones during night-time operations, ensuring more reliable and efficient crop protection efforts.
