Feature:
1. INNOVATIVE DESIGN: Adopting the concept of drop sensing design, the internal structure is specially designed to accurately control the size of raindrops, and then count the raindrops through the principle of optical sensing, so as to accurately measure the size of the rainfall.
2. COMPACT AND LIGHTWEIGHT: The rainfall sensor is small, lightweight and easy to install. This makes the sensor easy to install and use in a variety of applications, increasing user convenience.
3. EASY MAINTENANCE: It is not easy to wear and tear, easy to maintain. The rain cone is removable for cleaning. This design ensures the long term stability and reliability of the sensor.
4. HIGH ACCURACY: The accuracy is +/-4percent (indoor static test, rain strength is 2mm/min). The high accuracy of the measurement results can provide accurate data support to meet the user"s demand for accurate detection of rainfall.
5. WIDELY USED: The rainfall sensor is widely used in industries and fields such as smart agriculture, smart irrigation, ship navigation, automatic door and window, geological disasters, and so on.

Wiring:
Red Wire: Power positive
Black Wire: A+
Yellow Wire: B-
Green Wire: Power negative
Cleaning Method:
The sensor should be inspected regularly to remove dust, mud, sand, leaves so as not to block the water flow channel, resulting in no data or inaccuracy. Cleaning can be done by first removing the 3 top wires on the side of the edge ring, then removing the 3 screws of the cone and wiping them with water and a soft cloth.
Troubleshooting
1. The meter display value is incorrect when RS485 is output. It may be due to wiring problems or communicating serial port failure resulting in the inability to obtain the correct data. Please check whether the wiring is correct and firm, whether the serial port is occupied and whether the serial port is set correctly;
2. Display meter indicates that the value is obviously inconsistent with the actual situation. Please clean the sensor bucket, funnel, etc., and then test according to the experimental test method..
Package List:
1 x Rainfall Sensor1 x Instruction Manual
Note:
1. Please check whether the package is intact, and check whether the product model is consistent with the selected model. Do not connect with electricity. Do not turn on the power until the wiring is completed and checked.2. The length of the sensor wire will affect the product output signal, do not change the components or wires that have been welded at the factory, if there is a need to change, please communicate with the manufacturer.3. The sensor should be regularly checked to remove dust, mud, sand, leaves, so as not to block the upper cylinder (funnel) water flow channels, long term work generally need to be cleaned up once a month, three months must be cleaned up once.4. Dust on the inner wall of the hopper can be rinsed with water. It is strictly prohibited to use fingers or other objects to wipe, so as not to smear the oil or bruise the inner wall.5. During winter icing, the instrument should be out of use and can be taken back indoors.
