🔧 Frequently Asked Questions (FAQ)

What is a car distance sensor and how is it used in irrigation?

A car distance sensor is a type of laser or ultrasonic sensor typically used for measuring distances in vehicles. In irrigation applications, these sensors are repurposed to detect tree trunks or objects in the path of a water tanker, enabling automatic watering based on object proximity.

Can car distance sensors operate accurately in outdoor sunlight?

Yes, high-quality car distance sensors, especially laser-based models with sunlight-resistant features, are designed to work effectively in bright outdoor environments. Look for sensors with narrow beam divergence and ambient light suppression.

Why is RS485 output important in smart irrigation systems?

RS485 is a robust, long-distance communication protocol that allows reliable data transmission between the sensor and control systems in harsh outdoor conditions. It ensures precise coordination between the detection system and the water spraying mechanism.

How does the sensor detect tree trunks specifically?

The sensor emits a laser beam or ultrasonic pulse toward the roadside. When the beam hits a tree trunk, the reflected signal returns to the sensor, triggering a watering action. Proper positioning and beam alignment ensure accurate trunk detection without false positives.

What protection rating should the sensor have for outdoor use?

An IP67-rated sensor is highly recommended. This rating ensures complete dust resistance and protection against water immersion—ideal for use on moving vehicles exposed to rain, mud, or irrigation water.

Can the sensor differentiate between trees and other objects like poles or pedestrians?

Basic sensors detect any object within range, but more advanced models can integrate with AI or use filtering logic based on object size, distance, or movement patterns to distinguish tree trunks from other roadside obstacles.

Is this sensor compatible with my existing irrigation system?

If your system supports RS485 or analog input, integration is usually straightforward. However, ensure your control panel can interpret the distance signal and trigger irrigation actions accordingly.

How far can the sensor detect objects?

Meskernel’s laser distance sensors support detection ranges up to 5000 meters, with models customizable based on specific distance requirements. For smart irrigation tasks like roadside tree watering, we typically recommend models with ranges of 40m, 100m, or 200m, depending on the application scenario. You can contact Meskernel for expert guidance and customized sensor solutions tailored to your needs.

What is the typical accuracy of such sensors?

Our laser distance sensors offer precision up to ±1mm, using advanced time-of-flight measurement technology. However, for irrigation applications, such high precision is often not necessary. A standard accuracy of ±3mm is usually sufficient for reliable trunk detection. For example, our LDJ-200m green laser sensor is specifically optimized for outdoor use with high visibility and stable performance in demanding environments.

Where can I purchase a suitable sensor for this application?

You can purchase directly from Meskernel, a leading manufacturer with over 20 years of experience in laser distance measurement technology. We offer a full range of IP67-rated, RS485-compatible laser sensors built for rugged outdoor conditions.
