Shunt arduino
Web0. Basically, I want to measure the voltage across a shunt resistor (1.12mOhm) and feed that to an arduino analog input to obtain a measurement of a current drawn from a battery. I would like to obtain a sensitivity of about 0.1A (0.112mV), hence being the lowest readable voltage above zero, and the maximum expected current is about 40A (44.8mV).

WebJan 6, 2024 · Amplification with an operational amplifier (op amp), A/D conversion via the Arduino. Selection and use of the shunt The agony of choice. As with the INA219 and INA226, I chose 0.1 ohms for the shunt. The smaller the resistance, the smaller the signal. The greater the resistance, the greater the interference with the system to be measured.
WebAug 7, 2014 · The plan is to use a 10A 75mV current shunt as a current sense resistor then use an opamp to amplify the voltage across the shunt resistor then use the Arduino's onboard ADC to measure the voltage then calculate current using ohm's law. Here are my calculations: 10A full scale = 75mV across the shunt resistor. 1A = 7.5mV. WebJun 2, 2024 · In this video you will learn how to measure DC current and display it on TM1637 LED display.

WebThe source voltage is 3.3V and the load voltage is actually the LED voltage. The current passing through LED is also calculated using the shunt voltage. The shunt resistance creates a very small potential difference called the shunt voltage. These parameters will be displayed on the Serial Monitor: Bus, Shunt and Load voltage, current and power:
WebMy shunt is at a max rating of 10A (100mV max). The output of the shunt goes into a ad623 amplifier which I setup to get a 10x gain (because the mV would be too small to get good …
