A battery-powered weather station, designed by AI

Battery designs add a charger, power-path, and careful power budgeting to the usual sensor-node recipe. Describe what you want to measure and how it should charge, and Ohmni delivers a compact board that runs on a cell and tops up over USB-C.

What ends up on the board

  • Single-cell Li-ion battery with USB-C charging
  • ESP32 module for WiFi and logging
  • BME280 temperature, humidity, and pressure sensor on I2C
  • Status LED
  • Compact layout for a small enclosure

How Ohmni designs it

  1. The circuit is generated from your description: charger, power path, sensor wiring, and values calculated.
  2. Power rails are simulated and the layout is checked against manufacturing rules before you see it.
  3. You download gerbers, a BOM, and a 3D preview, ready for your fab.
