Electric energy meter is an instrument used to measure electric energy, also known as watt - hour meter, fire meter and kilowatt-hour meter. It refers to an instrument used to measure various electrical quantities. Electric energy meter (can be divided into coin – operated meter, magnetic card – operated meter, and electric card – operated meter), loss electric energy meter, multi-function electric energy meter, and intelligent electric energy meter. According to the electronic energy meter working principle : it can be divided into inductive (mechanical) meter, static (electronic) meter and electromechanical integrated (hybrid) meter. According to the nature of the connected power supply: it can be divided into AC meter and DC meter. According to structure: it can be divided into integral meter and split meter. According to access phase line: it can be divided into single phase meter, three phase meter and three-phase four-wire electric energy meter.You can find phase meter work

Wifi will enter standby mode when there is no data transmission. There are two situations in this situation: 1. If there is no AP connection, the wifi chip will enter deep sleep. At this moment, it is completely controlled by the master control, and the power consumption is shown as uA level on wifi power consumption meter. 2. When the AP is connected, the wifi chip will enter the sleep mode, but it will automatically get up to check the data. The wake-up period depends on the DTIM interval of the router AP (this value depends on the AP's ability to cache data). The value of DTIM interval is the interval of n Beacon, which is set to 1 by default. At this point DTIM interval is equal to beacon interval. Generaly speaking, when DTIM is equal to 1, the average current is 1mA. Of course, this value means that in the case of no data transmission and reception, wifi chip continues to sleep when waking up at regular intervals. This is also the most important low power consumption indic

In the laboratory monitoring project, different laboratories all have requirements on temperature and humidity, and most of the experiments are carried out in a clear temperature and humidity environment. In the fields of medicine, biochemistry, instrument calibration, agriculture, architecture and electrical appliances, laboratory environmental conditions directly affect the results of various experiments or tests. Accurate and reliable monitoring instruments are required for each experiment to provide accurate environmental parameter data. Lab temperature monitoring system fundamentally strengthens the supervision and quality improvement of medicine. Realize real-time display and multiple display, real-time record, long-term storage, timing backup, and rich alarm function, remote network monitoring, strict management authority and the reliability of the original data. 1. Real-time monitoring and multiple displays The temperature and humidity collection card can collect the enviro

Laboratory Temperature Monitoring System Laboratory temperature and humidity monitoring system is widely used in the laboratory and its purpose is to create a good laboratory environment for users and make the laboratory environment in the best working state. Therefore, it is necessary to display and record the actual temperature and humidity values of each laboratory. In addition to, the lab temperature monitoring system can keep abreast of the environmental conditions of each laboratory, so that managers and visitors can have a more scientific and timely understanding of the environmental information of the monitoring area. The characteristics are as follows: 1.It can improve work efficiency and with no need of manual recording. 2.Real-time view of the temperature in the environment under test. 3.When the temperature and humidity exceeds the limit, different alarm methods (such as SMS alarm, telephone alarm, mail alarm, etc.) can be used to prompt the management personnel, so tha

Laboratory Temperature and Humidity/ Laboratory Room Temperature And Humidity Control In laboratory monitoring projects, different laboratories have laboratory temperature and humidity requirements, and most of the experiments are conducted in an environment of clear temperature and humidity. Laboratory environmental conditions directly affect the results of various experiments or tests. Accurate and reliable monitoring instruments are required to provide accurate environmental parameter data for each experiment. The key factor to be considered in temperature and humidity control under environmental conditions is to ensure that the environmental temperature and humidity of the experimental operation can meet the needs of each process of the experimental program. We mainly formulate the range of environment temperature and humidity control in laboratories control from the following aspects. First of all, identify the requirements for environmental temperature and humidity. We mainly
