This IC is an amazing little thing because it takes a lot of the number crunching away from the Arduino and just sends the data over I2C that you need. Your schematic implies that you have separate, isolated power connections, The solar-shunt and the load-shunt. A device to measure electric current is called an ammeter. About 6% of these are sensors, 1% are pressure sensors. Low Power WiFi Datalogger. Adafruit Industries, Unique & fun DIY electronics and kits INA219 High Side DC Current Sensor Breakout - 26V ±3. This project is published under the terms of the GNU General Public License, version 3 licence. Adafruit INA219 DC High-Side Current Sensor breakout board MCP6002 dual op-amp (CMOS) TIP41C BJT transistor and external power supply Electrical prototyping board Jumper wires [If amplifying the 5V DAC signal, extra components: *External power supply 10kOhm resistors x3]. For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. The PV and TEG currents were measured using INA219 based sensors, with a resolution of 0. Internet of Things, Smart Home, Wireless Sensor Networks, ESP8266 Firmware Builder, ESP32 Firmware Builder, RTL87XX Firmware Builder, NRF24LE1 Firmware Builder, WiFi IoT. Voltage measurement range is 0 to 26 volts with 4 mV resolution and current measurement range is -4 to +4 amps with 1 mV resolution (when using a 0. The Arduino has analog and digital pins. A battery-powered fueling data collection unit for use with a meter and a register associated with a fuel transfer apparatus and for use with a system for managing fueling transactions of a fleet oper. I also need to measure a current up to 1A and I have found a chip INA219. This breakout board will solve all your power-monitoring problems. I have a CJMCU Breakout board and have it wired to my Electron. The sensor’s maximum resolution is 1080p and supports the connection of an IR LED, so that it can operate in a low lux (night vision) environment. 8 out of 5 stars 23. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the. This is Part 3 of the SmartMon Extension Board series. Figure 7’s conceptual schematic shows a multi-cell monitoring version.

If the I2C address needs to be modified, configure A0 and A1 to 0 or 1 respectively by the DIP switch on the module, and modify "_INA219_I2C_ADDRESS_x", the second parameter of "ina=INA219(1, _INA219_I2C_ADDRESS4)" in “getVoltageCurrentPower. It is an op amp buffer and an op amp comparator in series; I actually used a circuit similar to Dave Jone's uSupply current sense part hoping I won't forget anything and it could just work. com are licensed under a Creative Commons Attribution-NonCommercial 4.
