This is the best equipment for measuring rainfall at many farm weather stations. It is very helpful for large farms and small to medium-sized farms.
2.1 Working Principle of Tipping Bucket Rain Gauge Sensors
The main working principle of the tipping bucket rain gauge sensor is simple. It uses a tipping bucket to measure rainfall. This bucket converts the rain into electrical signals through three important steps.
First, rainwater goes into the sensor’s water-collecting funnel. This funnel is usually made of smooth polycarbonate or stainless steel. These materials help prevent water from sticking.
The funnel has a diameter of 200mm. It meets World Meteorological Organization standards for good and even collection.
The collected rainwater flows steadily into the lower tipping bucket. This bucket is a light, mechanical structure made of aluminum alloy. It has two equal chambers separated by a baffle.
When rainwater in one chamber reaches a set level (usually 0.1mm or 0.2mm of rain), the tipping bucket flips. This happens because of a shift in center of gravity. The bucket pours out water while the other chamber begins to collect.
Flipping makes a pulse signal with a magnet and a reed switch. Each pulse matches a set amount of rainfall, like 0.1mm. A data collector counts the pulses. This helps to find the total rainfall and its intensity.
2.2 Key Structural Components
The tipping bucket rain gauge sensor has precise mechanical parts and electronic modules. Its stable operation depends on the coordination of these components. The water-collecting funnel is key for gathering rainwater. Its size and material help it work well and resist wind and dust.
The tipping bucket is a key part of the measurement system. Its bracket and bearing affect how well it measures and stays stable. Low-friction bearings, like gem bearings, help reduce wear and increase service life.
The signal output module includes a reed switch, a magnetic sensitive switch, and transmission lines. It changes mechanical flipping into electrical signals that can be sent. Some models also have lightning protection for outdoor use.
The shell has IP65+ protection. This makes it both dustproof and waterproof. It works well in tough outdoor conditions. The adjustable base can be installed horizontally. This helps to avoid measurement errors.

They use data analysis to support farming. They monitor weather in real-time and give early warnings. This helps guide scientific farming. It also helps manage resources better, lowers losses from disasters, and boosts yield and quality.
Rainfall is important for crop growth. It is the main water source for crops. It is also linked to drought, floods, soil erosion, and crop diseases.
Rainfall monitoring is a key job for agricultural weather stations. The accuracy of this data directly impacts their service quality.
The tipping bucket rain gauge sensor is key for rainfall monitoring. It collects and converts data. This helps track rainfall reliably. It also links weather data to actual farming results.
4. The Important Role of Tipping Bucket Rain Gauge Sensors in Agricultural Meteorological Stations
In agricultural weather stations, the tipping bucket rain gauge is more than just a tool. It helps with better management, disaster prevention, and scientific decision-making.
Its role includes managing crop growth, water use, disaster alerts, and planning for production. This is mainly seen in these areas.
4.1 Providing Accurate Rainfall Data for Crop Growth Monitoring
Crop growth depends a lot on rainfall. Different crops and growth stages need different amounts of water. Too little or too much rain can lower yield and quality.
The tipping bucket rain gauge sensor monitors rainfall on farmland. It records total rainfall, intensity, duration, and frequency in real time. The sensor sends this data to the meteorological station’s analysis system.
Technicians use this data along with crop growth and soil moisture. They check if there is enough water, see how rainfall affects crops, and make specific suggestions.
For example, its high resolution records small amounts of rainfall (0.1-0.5mm). This is important for wheat and corn germination.
It helps manage extra watering. Current data shows when heavy rain is likely. These risks include poor ventilation, diseases, and lodging during crop heading and filling.
This information leads to better drainage and field management. Long-term data helps us study regional rainfall patterns. This helps in choosing the right crop types and changing planting methods to improve production stability.
4.2 Guiding Scientific Irrigation and Optimizing Agricultural Water Resource Utilization
Water resources are very important for farming. However, poor irrigation practices waste water. This can lead to soil salinization and compaction.
The tipping bucket rain gauge sensor gives real-time and accurate rainfall data. This helps solve the problem and improves water use.
The meteorological station uses rainfall data, soil moisture, and crop water needs. It calculates water shortages for farmland.
Then, it creates smart irrigation plans. This helps with focused watering. It means giving more water during dry times and stopping when it rains.
In dry North China, real-time rainfall monitoring sends irrigation reminders. It also calculates the right amount of water needed. This helps use water-saving methods like drip and sprinkler irrigation. These methods can save over 30% of water compared to flood irrigation.
Advanced stations connect sensors to smart irrigation systems. These systems automatically change the watering time and amount based on real-time rainfall. This allows for unattended operation, boosts efficiency, cuts labor costs, and supports water-saving and smart farming.
4.3 Early Warning of Agricultural Meteorological Disasters and Reduction of Disaster Losses
Agricultural weather disasters, like droughts, floods, and waterlogging, lead to big drops in crop yields and economic losses. The tipping bucket rain gauge sensor is important for early warning. It monitors rainfall changes in real-time. This helps us take preventive measures ahead of time.
For flood and waterlogging, it checks the amount and intensity of rainfall. If it goes over a set limit, like 30mm/h, the station sends out early warnings. This helps with drainage, early harvests, and strengthening greenhouses.
These actions are important in southern rice-growing areas during the rainy season. They help reduce damage from waterlogging. To track drought, we collect long-term rainfall data.
When rainfall is much lower than the average and soil moisture is low, we issue drought warnings. These warnings help us save water and keep the soil moist. This ensures that crops can grow normally.
