RY-YLX rain bucket sensor
The RY-YLX tipping-bucket rain gauge measures precipitation by converting rainfall into a quantifiable physical signal. It is widely used in small meteorological stations, hydrological stations, and relevant agricultural and forestry departments to measure precipitation volume, intensity, and duration. It outputs a pulse signal, and the amount of rainfall is determined by recording the number of pulses.

مقدمة
A rain bucket sensor (also known as a tipping bucket rain gauge) is a meteorological instrument used to measure rainfall accurately. It works by collecting rainwater into a small bucket that tips once a predefined volume is reached, triggering a signal for each tip. By counting the number of tips over time, the sensor calculates total precipitation and rainfall intensity. It is widely used in محطات الطقس, agriculture, hydrology, and environmental monitoring due to its reliability, simple structure, and suitability for long-term outdoor deployment.
Rain bucket sensor working principle
Rainwater is collected at the inlet and fed into the measuring hopper through the inlet. When the water level reaches a preset value, the measuring hopper tips over. As it tips, a magnet passes over a reed switch, causing it to activate once and send a pulse signal representing 0.2 mm of rainfall. This signal is recorded by the instrument, enabling automatic data collection.
Structure Rain bucket sensor
- Collecting Funnel: Collects rainfall and directs the water evenly into the internal measuring mechanism.
- Tipping Bucket: The core measuring component; it tips once automatically when the preset water volume is reached.
- Pivot & Bearings: Support the smooth rotation of the tipping bucket, ensuring sensitivity and repeatability.
- Reed Switch / Hall Sensor: Triggers an electrical signal output each time the tipping bucket moves.
- Signal Output Unit: Converts the number of tipping bucket movements into rainfall data (pulse or digital signal).
- Housing & Base: Protects the internal components and typically features waterproof and corrosion-resistant properties.
- Drainage System: Quickly drains rainwater after the tipping bucket moves to prevent water accumulation from affecting measurements.
- Leveling Device: Ensures the device is installed level to improve measurement accuracy.
