KY rain sensor KY-A1

Rain sensor
The series of switching output rainfall sensors can be widely used in small weather stations, hydrological stations, agriculture and forestry and other relevant departments to measure precipitation, precipitation intensity and precipitation time. Output pulse signals and measure the size of rainwater by recording the number of pulses.

Technical parameters
Water-bearing diameter
Measuring range/
Output signal: single reed switch on and off
Weight: about
Signal output: Red line: signal output positive, black line: signal output negative
Working principle
The water receiving port collects rainwater and pours it into the metering tipping bucket through the water injection port. When the injected water volume is reached, the tipping bucket flips, during the flipping process
The magnetic steel passes through the reed switch, causing the reed switch to switch once, sending out a pulse signal, representing precipitation, which can be recorded by the instrument for automatic collection.
The rain sensor is composed of a water receiver, a water guide funnel, a sensor mounting bracket cover, etc. The diameter of the water container is 2. The rainwater is introduced into the internal sensing device through a conical water-conducting funnel for measurement. The rainfall data is transmitted to the internal microcontroller of the instrument through a connecting cable for processing and storage. At the same time, the current rainfall value is displayed on the instrument display. display. At the same time, the historical rainfall change curve can be displayed and viewed. Through button operation, the rainfall changes on different dates and different time periods can be viewed

Notes
The water receiver should be kept clean every time. Clean and inspect it at least once a month, and keep the dust cover closed when not in use.
When not in use for a long time, the instrument should be powered on every ~ months to ensure normal operation of the instrument.
Indoor instruments should not be placed in a dusty and humid environment for a long time. The instrument should not be placed in an environment with corrosive gases or exposed to the sun

High precision and good stability
Volume Small, easy to install
Good linearity, long transmission distance, strong anti-interference ability
The tipping bucket component support system is well-made and has small friction torque, so the tipping bucket component flips sensitively, has stable performance and reliable operation
The instrument shell is made of stainless steel, with strong anti-rust ability and good appearance quality
The rain-bearing opening is made of stainless steel skin that is punched and drawn as a whole, with high smoothness and small errors caused by water retention
Scope of application:
The sensor is a hydrometeorological instrument used to measure rainfall in nature to meet the needs of information transmission, processing, recording and display. It can be used by relevant departments such as meteorological observatories (stations), hydrological stations, agriculture, forestry, and national defense field reporting stations, and cooperates with the rainfall recorders independently developed and produced by our company to measure precipitation, precipitation intensity, precipitation time, etc. It can provide original data for flood control and water supply dispatching power station reservoir water regime management.
