Arduino MQ135 Gas Sensor first, the wiring The MQ135 has 4 pins, VCC, GND, A0, D0, respectively, where VCC, GND, and A0 are required. The following diagram is a esp8266 wiring diagram. Due to the measurement of the gas value of PPM, it is related to the air temperature and humidity. So we've added a DHT22 here.

insufficient when the Create table statement is executed in the stored procedure. I tried to change the stored procedure to an anonymous stored procedure and run it in PL/SQL. Since the statement passed. This indicates that this statement is correct and the problem occurs during the stored procedure. I am using a DBA account to log on to the system. It is reasonable that there should be no insufficient permissions. Where else is the problem? By checking the information online, we found that Ora

With our interpretation, the computer structure has become clearer and clearer. We know that computer commands are combined into programs to control hardware work, this cleverly controls the same hardware by writing different software to complete different tasks to enhance system flexibility. We also know that computer commands are nothing more than transmitting data for computation. But we still don't know how the computer controls the execution of each command. CPU Internal ControlLike the PC

we do not know what is on the other side of this abstract obstacle, we should doubt whether it is so good as to assume that it never throws an unknown exception. If the service routine throwsRuntimeException, The Calling thread should capture this exception, record it to the log, then switch to the next item in the queue or close the thread, and then restart it. (The last option comes from the assumption that any throwRuntimeExceptionOr the error code may have damaged the thread status .) The c

And in statistical signal analysis, it is seldom seen with R.Well, in fact, I am not an IR expert, but I like IR, in recent years the domestic research in this area is quite a lot of people, Google and Baidu's strong, also shows the value of this direction. Of course, if you are studying
