Product description: INA228 - current and power sensor - I2C - STEMMA QT / Qwiic - Adafruit 5832
A compact proposition from Adafruit equipped with the INA228 system, which allows you to monitor the power in the circuit. It allows you to measure voltage with a maximum value of 85 V DC and current up to 10 A. Moreover, it also has a 20-bit ADC converter that increases the precision of measurements. Not suitable for measuring alternating currents. Works with boards such as Raspberry Pi and Arduino.
INA228 - current and power sensor - I2C - STEMMA QT / Qwiic - Adafruit 5832.
Compatible with Raspberry Pi and Arduino.
Special features of the current and power sensor
- Measurement of voltages with a maximum value of 85 V DC in common voltage mode, measurement on a low or high voltage line.
- 20-bit ADC converter responsible for high measurement precision.
- I2C interface for communication with other devices (useful, for example, when triggering alarms).
- It is used in the implementation of projects related to energy management, as well as with all battery consumption indicators.
- Compatible with popular development boards such as Raspberry Pi and Arduino.
- It has easy-to-connect connectors - STEMMA QT / Qwiic and a 3-pin screw connector.
- It can be used to measure 85V/10A (~10uA per LSB) or 2.75A (~2.5uA per LSB) continuously.
