This project involves designing and implementing a voltage, current, and power meter circuit, leveraging the powerful RP2040 Zero microcontroller, the precision INA219 sensor, and a 3.2-inch ILI9341 SPI 320x240 TFT display. The RP2040 Zero, featuring a dual-core Arm Cortex-M0+ processor running...
I recently come up an idea to make IOT system debugging much easier. It is patent-able. Wondering if any of you are interested in working together to make it a good sale.
Here are more detailed info:
1. Measure current in 30nA resolution in real time. yet keep dynamic range in 30nA - 1A
2...
Hello there,
I am interested on a Current to Voltage Converter, that basic says, "A current to voltage converter will produce a voltage proportional to the given current".
This configuration can be used equally well for devices that source their current via some positive excitation voltage...
We are a developing a wearable device with BLE technology (BT Smart). We are not able to accurately measure battery life our device. The battery dies faster (about 30 days) than expected/calculated time of over 300 days. We can improve the performance once we have better measurement accuracy...
