Model: PZEM-004Tv3 Interface: RS485 Power supply: 5V Data type: A energy Usage: indoor Measuring range: 0...9999 kW*h Resolution: 1W*h Price: 5 USD Sensor life, years: 2+ Datasheet: PZEM-004Tv3.pdf Remarks: Energy consumption meter. In the event of a prolonged power failure, the readings are lost. After filling the scale, the measurement starts from 0. Stable operation, in contrast to v1. RS485 protocol, but does not require a special converter for connection. To work with ESP, it is necessary to halve the value of the resistors on the optocoupler. Additionally, it can measure frequency and power factor.
