Description

DIY depth gauge that allows you to measure how deep you are, or were, diving. Consists of a micro:bit, a battery pack, an edge connector, a BMP280/BME280 barometric pressure sensor and jumper cables. All packed into two layers of watertight clear plastic or silicone bags, supported by some weights to compensate the buoyant force.
