51WS3 weather interface module data storage and calculation description
After rolling calculation, the rainfall values of the previous minute, the previous hour and the previous 24 hours were obtained
After rolling calculation, the real-time wind speed, the average wind speed in the first 1 minute and the maximum wind speed in the first 5 minutes were obtained.
Temperature: temperature, humidity and pressure data shall be read every 5 seconds
Note:
JP1 short connection =ARS British mode,JP1 open circuit = professional metric modeOutput one measurement at an interval of 0.5 seconds.
APRS data output format (English, default) :
c000s000g000t082r000p000h48b10022*3COutput 38 bytes every 0.5 seconds, including the newline character at the end of the data (OD,OA)
Data analysis:
C000: wind direction Angle, unit: degree.*20 checksum, A and * (excluding *) all characters xor result
The interface board will automatically detect whether the air pressure piece, temperature and humidity sensor is installed, and the data of the sensor that is not installed will display "... ".The generation weather module supports the automatic identification of particulate matter sensor PMS5003 PMS5003ST
Default data format, including validation data format
:c000s000g000t086r000p000h45b09963*31
When it is detected that PMS5003 is installed, the data output is as follows:
Including PM2.5 and validation data formats: c000s000g000t082r000p000h43b09985, 027035040023032040, 14
Professional measurement data output format (metric) :
Short JP1, JP1=0 British, open road JP1, JP1=1 metric system
After electrification, into the professional measurement mode, convenient for secondary development.
DATA interface 9600, 2400 speed
Professional measurement data format:74 bytes are output every 0.5 seconds, including the newline character (OD,OA) at the end of the data.
Data analysis:
A0789: real-time measurement of wind direction AD value (0-4095)M703: humidity 0.1 (0% = 99%)
N10233 pressure (0.1hpa)
*27 checksum, A and * (excluding *) all characters xor results
51WS3 calibration and adjustment function
51WS3 supports the ability to calibrate data, which can be used when the original data values need to be adjusted in some special circumstances.51WS3 factory default is that the temperature, humidity and pressure are all the original data output, that is, no addition or subtraction.
1. Connect the USB to TTL data cable (optional), connect 51WS3, open the general serial port debugging software, and select the correct port number with the rate of 9600.
2, send the instruction AT+SET=T+000H+000B+0000 carriage return, that is, the setting is finishedNote: all setup commands require + ENTER.
Command: the AT + VER =? enter
Note: displays the current firmware version number
Command: AT+SET=T+000H+000B+0000 enter
Description: add and subtract the original data of temperature, humidity and air pressure
Instruction,
The AT + SET = T + 000 h + 000 + 0000 bT+000 represents temperature +00.0 ° c (in degrees Celsius), calibration range +-99.9
Note: this calibration value is metric Celsius.
H+000 represents humidity +00.0% and calibration range +-99.9
Calibration addition, if the measurement of humidity + calibration value, more than 99.9%, then fixed to 99.9%B+000 represents air pressure +000.0hpa and calibration range +-999.9hpa
For example:
Raw data: c000s000g000t082r000p000h49b09957New data: c000s000g000t082r000p000h41b08957
51WS3 weather interface module data storage and calculation description
Rainfall: the 51WS3 weather interface board is equipped with 1440 bytes of rainfall data cache to record the rainfall data samples per minute.
After rolling calculation, the rainfall values of the previous minute, the previous hour and the previous 24 hours were obtained.
Wind speed: 51WS3 weather interface board built-in 300 bytes wind speed data cache, recording the real-time wind speed sampling value every second.
By rolling calculation, real-time wind speed, average wind speed in the first 1 minute and maximum wind speed in the first 5 minutes were obtained.
Temperature: temperature, humidity and pressure data shall be read every 5 seconds
