Exceeding the value - turn on the relay.

[stsxbel]

Good afternoon, I can’t figure out how to write the code. We read the value from the database, if it exceeds, say, 2000, then we turn on the relay via GPIO.

How to read - I understood.

import struct
import sys
import time
import datetime
import pymysql.cursors
import wiringpi
from wiringpi import GPIO

connection = pymysql.connect(host='127.0.0.1', user='root', password='2548695542', db='sd', charset='utf8mb4', cursorclass=pymysql.cursors.DictCursor)

with connection:
    cur = connection.cursor()
    cur.execute("SELECT * FROM ddd1 ORDER BY id DESC LIMIT 1")
    rows = cur.fetchall()

    for row in rows:
        print(row["weight"])

How to turn on the relay - too.

NUM2 = 2    # (wPi-2) orange pi zero 2

wiringpi.wiringPiSetup()

wiringpi.pinMode(NUM2, wiringpi.GPIO.OUTPUT);

wiringpi.digitalWrite(NUM2, GPIO.HIGH);

But I can’t figure out how to connect this together. :-(
