Ambient
About the Ambient PCB
Ambient is an open source PCB design by PolygonHJ, published on GitHub under the MIT license. It is a 2-layer board measuring 12.5 × 11 mm, with 9 components from 6 distinct parts.
Other key parts include the OPT3002DNPR and HDC2010YPAR. By type, the board carries 3 resistors, 2 ICs, 2 capacitors, 1 connector and 1 switch.
It belongs with the iot & wireless and sensors designs in this gallery.
From the project
Xihe is a self-sustaining, ultra-low-power sensing platform designed for long-lifetime deployments with zero maintenance.
The system is designed to be as small and unobtrusive as possible, enabling it to be placed in an environment, monitor passively, and be forgotten—both visually and in terms of maintenance.
Example sensing applications: - Light - Temperature - Humidity - Moisture - Open/Close (e.g. reed switch)
