DDSY866 Single-phase electronic energy meter (Prepaid for mobile Bluetooth scanning)

Product Overview

This product adopts an advanced microcontroller processing system for data acquisition, processing, and storage. It adds Bluetooth communication function on the basis of traditional IC prepaid electricity meters, and connects with mobile phones through Bluetooth communication to achieve the function of mobile phone prepaid electricity bills. At the same time, it has the characteristics of high precision, high reliability, high overload, and low self power consumption. The backend system interface design is simple and beautiful, the process operation is convenient, and users are easy to use. It perfectly solves the difficulty of collecting electricity bills from landlords and is suitable for scenarios such as apartments, property management, parks, and campuses. The main functions are as follows:

• 1) Online collection: The landlord adds a WeChat Alipay collection account through the WeChat applet, and the tenant directly arrives at the account bound to the landlord after paying the electricity bill;

• 2) Online payment: tenants can pay online by scanning the QR code of the meter, and support WeChat Alipay dual platforms (Bluetooth communication is 10 meters away from obstacles);

• 3) Automatic closing: When the balance of the electricity meter recharge is "0", the system automatically closes the switch. The landlord can also remotely turn on and off the electricity meter by connecting it via Bluetooth through the WeChat mini program.
