Model: INA226 Interface: i2c Power supply: 2.7...5.5V Data type: I current Usage: indoor Measuring range: -81.92...81.92 mV Resolution: 2.5 uV Price: 1-2 USD Sensor life, years: 2+ Datasheet: INA226.pdf Remarks: The Sensor is interesting, due to the increased measured voltage, the claimed works up to 36 V, up to a maximum of 40V, but is not recommended. A standard 0.75 mV shunt can be installed, and as a result, any DC currents can be measured. The sensors have a short response time.

Model: PZEM-004Tv3 Interface: RS485 Power supply: 5V Data type: I current Usage: indoor Measuring range: 0.05...100A Resolution: 0.001A Price: 5 USD Sensor life, years: 2+ Datasheet: PZEM-004Tv3.pdf Remarks: Two connections are possible, through a built-in resistor (up to 10A) and through a current transformer (up to 100A). Stable work, unlike 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.
