IoT prepaid electricity meter

Introduction:

High quality, high-precision, high-sensitivity, high stability, wide range, low-power dedicated metering chips and high-quality specialized components designed specifically for electronic energy meters are produced using advanced SMT technology for IoT prepaid electricity meters. The way the Internet of Things forms a network is also very simple, it can be wired, wireless, GPRS， LAN format, etc. Internet of Things prepaid electricity meters use advanced microelectronics technology for data collection, processing, and storage, using collectors to receive and transmit data, and water meter manufacturers will provide supporting software.

Introduction to the advantages of IoT prepaid electricity meters:

1. The main feature of IoT prepaid electricity meters is online recharging, where users can log in to the system at any time through their mobile phone or computer to check their electricity and bill.

2. The system will also automatically notify payment, and the payment process can be completed online anytime and anywhere, without the need to go to the business office specifically, and there will be no situation where electricity cannot be used due to business hours.

3. It has the characteristics of long service life, strong anti-interference and attack resistance, wide voltage and temperature working range, and is particularly suitable for the transformation of two networks. It is the current reform of the electricity system.

4. The ideal product for commercializing electricity, solving the difficulty of charging fees, and improving the load status of the power grid.

Internet of Things prepaid electricity meter price reference:

1. 1.5 (6) A: 450 yuan to 550 yuan per unit;

2. 5 (20) A: RMB 550 to RMB 650 per unit;

3. 10 (40) A: 700 to 800 yuan per unit;

4. 20 (80) A: 800 to 1200 yuan per unit.

The IoT prepaid electricity meter is a smart meter independently developed by our company for remote meter reading and valve control. It communicates remotely with servers through Narrowband Internet of Things (NB IoT), eliminating the need for devices such as collectors or concentrators, simplifying equipment installation work, achieving automatic remote meter reading of electricity meter usage, and effectively avoiding the manual work of management departments for on-site meter reading. Under the trend of the Internet of Things, the He Yuan intelligent smart electricity sensing terminal integrates electrical safety monitoring, power monitoring, energy metering management, and energy quality analysis, and can be applied to various new or renovated projects.
