Model: INA226 Interface: i2c Power supply: 2.7...5.5V Data type: U voltage Usage: indoor Measuring range: -40...40V Resolution: 1.25 mV Price: 1-2 USD Sensor life, years: 2+ Datasheet: INA226.pdf Remarks: The Sensors are interesting, due to the increased measured voltage, claimed to work up to 36V, up to a maximum of 40 V, but do not recommend. The sensors have a short response time. | |
Model: PZEM-004Tv3 Interface: RS485 Power supply: 5V Data type: U voltage Usage: indoor Measuring range: AC 80...270V Resolution: 0.1V Price: 5 USD Sensor life, years: 2+ Datasheet: PZEM-004Tv3.pdf Remarks: Recorded voltage readings up to 270 V. 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. |
