About Open Sense

Open Sense is a citizen science open environmental sensing platform. It puts environmental sensing in everyone's hands, the sensors, the data, and the whole design, open to anyone who wants to measure the world around them.

I am building the first node for myself. It rides on the back of my chair, with a panel on the headrest that shows the readings right where I am, in real time, for anyone near me to read. I built it because I wanted it. I opened it because everyone should be able to have one.

The data belongs to the person who gathered it. Every reading goes into a record that can never be quietly changed, and you always hold the key to your own data. No one else reads it unless you decide they can.

And it is open all the way down. The entire design, the full bill of materials, the construction instructions, and the source code are available under the MIT license. Take it. Add the sensors you care about, remove the ones you do not, and build the version that watches what matters to you. Make it your own.

Built by me, here for anyone. One node becomes many, each one owned by its builder, all of it feeding an open record that nobody controls. That is how a gadget on one chair becomes a movement.
