1. If equipped with a weather station produced by the company, directly connect the sensor to the corresponding interface on the weather station using a sensor line;

2. If the sensor is purchased separately, as the sensor outputs a set of switching signals, the cable connector does not matter positive and negative. Connect the sensor to the circuit as shown in the figure.

If the sensor outputs other signals, the corresponding line sequence and function of the conventional sensor are as follows:

Structure Dimensions 

Transmitter size  

1. the serial format
Data bits 8 bits
Stop bit 1 or 2
Check Digit None
Baud rate 9600 Communication interval is at least 1000ms
2. Communication format
[1] Write device address
Send: 00 10 Adress CRC (5 bytes)
Returns: 00 10 CRC (4 bytes)
Note: 1. The address bit of the read and write address command must be 00.
2. Adress is 1 byte and the range is 0-255.
Example: Send 00 10 01 BD C0
Returns 00 10 00 7C
[2] Read device address
Send: 00 20 CRC (4 bytes)
Returns: 00 20 Adress CRC (5 bytes)
Explanation: Adress is 1 byte, the range is 0-255
For example: Send 00 20 00 68
Returns 00 20 01 A9 C0
[3] Read real-time data
Send: Adress 03 00 00 00 01 XX XX
Note: as shown below:

Returns: Adress 03 02 XX XX XX XX YY YY
Note

To calculate the CRC code:
1. The preset 16-bit register is FFFF in hexadecimal (that is, all are 1). Call this register the CRC register.
2. XOR the first 8-bit data with the lower bit of the 16-bit CRC register and put the result in the CRC register.
3. Shift the contents of the register to the right by one bit (toward the low bit), fill the highest bit with 0, and check the lowest bit。
4. If the least significant bit is 0: repeat step 3 (shift again), if the least significant bit is 1: the CRC register is XORed with the polynomial A001 (1010 0000 0000 0001).
5. Repeat steps 3 and 4 until 8 times to the right, so that the entire 8-bit data has been processed.
6. Repeat steps 2 to 5 for the next 8-bit data processing.
7. The CRC register finally obtained is the CRC code.
8. When the CRC result is put into the information frame, the high and low bits are exchanged, and the low bit is first.

1. The installation position of the sensor can be selected on the ground, self-made big tube, iron pillar flange or on the roof of the house according to actual requirements.
2. Adjust the three leveling screws on the chassis to make the level bubble indication level (the bubble stays in the center of the circle), and then slowly tighten the three M8 × 80 fixing expansion screws; if the level bubble changes, you need to readjust.
3. Assemble and fix the sensor as shown in the figure above.
4. After fixing, open the rain bucket and cut off the nylon cable ties on the funnel, slowly inject fresh water into the rain sensor, and observe the turning process of the bucket to check whether the data is received on the acquisition instrument. Finally, quantitative water (60-70mm) is injected. If the data displayed by the acquisition instrument is consistent with the amount of injected water, the instrument is normal, otherwise it must be repaired and adjusted.
5. Avoid disassembling the sensor during installation.

1. Please check whether the packaging is intact and check whether the product model is consistent with the selection.
2. Do not connect line with power on. Only check the wiring and make sure the power is on.
3. The sensor cable length will affect the output signal of the product. Do not arbitrarily place the components or wires that have been soldered when the product leaves the factory. If there is a need for change, please contact the manufacturer.
4. The sensor should be inspected regularly to remove dust, mud, sand, leaves and insects, so as not to block the water flow channel of the upper tube (funnel). The cylindrical filter can be removed and washed with water.
5. There is dirt on the inner wall of the dump bucket, which can be washed with water or alcohol or detergent aqueous solution. It is strictly forbidden to wipe with fingers or other objects, so as not to get oily or scratch the inner wall of the dump bucket.
6. During freezing in winter, the instrument should be stopped and can be taken back to the room.
7. Please save the verification certificate and the certificate of conformity, and return it with the product when repairing.

1. The display meter has no indication. The collector may not be able to obtain the information correctly due to wiring problems. Please check whether the wiring is correct and firm.
2. The displayed value of the display is obviously inconsistent with the actual situation. Please empty the water bucket and refill the bucket with a certain amount of water (60-70mm), and clean the inside wall of the bucket.
3. If it is not the above reasons, please contact the manufacturer.

Rainfall sensor (transmitter) is suitable for meteorological stations (stations), hydrological stations, agriculture, forestry, national defense and other related departments, and is used to remotely measure liquid precipitation, precipitation intensity, and precipitation start and end time. This instrument strictly organizes the production, assembly and verification according to the national standards of tipping bucket rain gauge. It can be used for automatic hydrological forecasting system and automatic field forecasting station for the purpose of flood prevention, water supply dispatching, water regime management of power stations and reservoirs.
