What does the configure () method in INA219 PY do?

The configure method sets up the INA219. The voltage_range is set to 16 V. This is the full scale voltage range. The options are 16 V or 32 V.

How do I connect to INA219?

Connect to the circuit

1. Connect V+ to the positive terminal of the power supply for the circuit under test.
2. Connect V- to the positive terminal or lead of the load. This puts the sense resistor in-line with the circuit.
3. Finally, connect a wire from the negative terminal of the power supply to GND.

What is INA219?

The INA219 is a current shunt and power monitor with an I2C- or SMBUS-compatible interface. The device monitors both shunt voltage drop and bus supply voltage, with programmable conversion times and filtering. The INA219 senses across shunts on buses that can vary from 0 to 26 V.

What kind of voltage does Raspberry Pi ina219 measure?

It can measure voltage up to 26 volts. This board has a 0.1 ohm current measuring shunt resistor which is labeled R100. The INA219 chip can very precisely measure the voltage drop across the shunt. This is the difference between the voltage coming into the shunt and the voltage after the shunt.

How does an acs712 linear current sensor work?

The ACS712 is a fully integrated, hall effect-based linear current sensor with 2.1kVRMS voltage isolation and a integrated low-resistance current conductor. Technical terms aside, it’s simply put forth as a current sensor that uses its conductor to calculate and measure the amount of current applied. The features of ACS712 include:

What’s the latest version of the ina219 sensor library?

Version 1.1.0 of the INA219 library is now available with three major enhancements: Support for automatic gain adjustment, this makes getting valid readings over the full current/power range of the device very easy. Automatic gain is the default mode.

How to connect ina219 voltage and current sensing chip?

[5] 15 bit resolution is achieved by averaging for ± 3 20mV range. How to connect INA219: It’s simple just connect Vin+ to your supply voltage (this is the high side voltage), and connect Vin- to your circuit. Vin- also measures the voltage appearing at the attached circuit.
