README
README.mdENBLE
ENBLE is the ENvironmental sensor which measures temperature, humidity, and air pressure and sends them over BLE. Because it consumes little current, it can work several years.
Using bridge server and ThingsBooard which are runnning on Raspberry Pi3, you can collect data from some ENBLEs and view measurement data via web browser.
Contents of this repository
This repository consists of two components.
1. Sensor
It contains PCB design and firmware for a ENBLE device. The details is in README.md.
2. Bridge Server
It constains a bridge between ENBLE and ThingsBooard as a sample code to utilize ENBLE. Bridge server listens BLE advertise packets from ENBLEs and sends data to a ThingsBoard server. Using ThingsBoard enables you to collect and visualize measured data.

Questions
How big is the ENBLE PCB?
It measures 27 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ENBLE use?
18 parts, built around the BME280, CR2032 and SI2333. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ENBLE KiCad files?
From the idt12312/ENBLE repository on GitHub, at the commit this page was made from: the board is sensor/pcb/ENBLE.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ENBLE design in my own project?
Its repository states no licence, so its author keeps all rights: ask idt12312 before reusing the design.
