Battery Life Estimation Example

ZS1100A is designed to accurately measure energy consumption of low-power/IoT devices - establishing a current profile for the given device. This current profile can then be used by the host software to estimate the lifespan of a particular battery were it to be used in the device. This update walks through the process, using a wireless mouse as the target device. Read the full update.

The Campaign is Live

ZS1100A is a USB-based power supply that can accurately estimate the energy consumption of IoT devices. This tool can plot the current consumption vs time very accurately and in great detail, which can be used along with the battery model to estimate the overall battery life. The crowdfunding campaign has begun - check out the project page for more details and to place an order. Read the full update.
