One of our customers has created a new generation of capacitive sensing technology that is unique in its capacity to always be “ON” while using extremely little power. The customer is looking for a low-cost platform that can quickly demonstrate the low-power capability of this product in front of customers as well as in trade shows. Not only that but such a platform should be scalable and can be used with any of their other kits/products. Engibrains designed and developed an ultra-precise Current & Voltage measurement system with a cross-platform tablet app that displays instantaneous current and voltage reporting with a graph.


Engibrains offered TI – INA229 and BLE-based engineering solution which captures Instantaneous current range from 1 uA to 10000 uA and voltage range 1V to 6V. we also developed a configurable averaging window that can be used to control/configure/monitor average current and voltage reporting from the Tablet interface. For a hassle-free demo experience, we designed to plug-n-play solution along with a quick reference use manual.
