Arduino Project to Product-Part 7 How to Measure Small Currents

2019-08-05 | By Maker.io Staff

Arduino

The ability to measure small currents allows the designer to more accurately calculate project battery life. In this video, Shawn Hymel continues the tutorial on the LoRa project with respect to battery life by explaining how to program device sleep mode and use an amplifier to measure the resulting current reduction on an oscilloscope. Implementation of a current sense amplifier is demonstrated including component selection and PCB production using a Bantam desktop milling machine.
