Volt-Amp-Watt-Meter for Grove
|
Based on the INA219 from Texas Instruments and on the popular Grove system, I've developed this Volt-Amp-Watt-meter for Grove after the I²C Voltage-Current-Power INA219 Sensor.
The Volt-Amp-Watt-meter for Grove can be powered with 3.3 ~ 5 V and is connected to the I²C bus. The I²C address is configurable on the 0x40~0x4f range. The internal ADC of the INA219 has a 12-bit resolution. Changing the precision resistor allows to have a different range of measures. |
