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 indica

Electricity usage monitor is a necessary configuration in special occasions, such as the hospital. Due to the particularity of its work, the hospital still has the characteristics of dense personnel, large flow of people. Furthermore, the patient's treatment and life cannot be strictly distinguished, and the building equipment, building medical equipment and ward medical equipment are dense. From the aspect of power supply and distribution, level of the power supply load in the hospital is relatively high, the power supply and distribution mode are quite different from other civil buildings. There are many kinds of high-power instruments and equipment and the users lack professional knowledge of power consumption, causing many potential safety hazards of power consumption, for example, leakage current poses potential risks to patients, and power failure poses life risks to patients who are using instruments and are in urgent need of instruments for treatment. According to the curre

Accurate power monitoring is crucial for data center operators. It is crucial to ensure correct handling in order to track and improve power process. But most data centers’ power monitoring systems are overly complex and inaccurate. At the webinar, industry experts will explain how this has changed. There are five key requirements for power supply in any data center-availability, efficiency, sustainability, flexibility and customized billing. These five points are the cornerstones of a good power monitoring system for data center operators. However, many data center operators find it difficult to correctly manage and accurately measure their power consumption. At present, it requires at least three to four systems to measure the power of each point in the data center. Measuring power from transformer level to rack can be complicated and integration problems often occur due to many different monitoring systems (usually provided by different manufacturers). This situation can be c
