# Sensirion I2C SEN44 Arduino Library
This is the Sensirion SEN44 library for Arduino using the modules I2C interface.
# Installation
To install, download the latest release as .zip file and add it to your
[Arduino IDE](http://www.arduino.cc/en/main/software) via
Sketch => Include Library => Add .ZIP Library...
Don't forget to **install the dependencies** listed below the same way via `Add .ZIP Library`
Note: Installation via the Arduino Library Manager is coming soon.
# Dependencies
* [Sensirion Core](https://github.com/Sensirion/arduino-core)
# Quick Start
1. Connect the SEN44 Sensor to your Arduino board's standard I2C bus. Check the pinout of your Arduino board to find the
correct pins. The pinout of the SEN44 Sensor module can be found in the data sheet and here:
| *SEN44* | *Arduino* | *Jumper Wire* |
|---------|----------------|---------------|
| VCC | 5V | Red |
| GND | GND | Black |
| SDA | SDA | Green |
| SCL | SCL | Yellow |
| SEL | GND for I2C | Blue |
| *Pin* | *Name* | *Description* | *Comments* |
|-------|--------|---------------|------------|
| 1 | VDD | Supply Voltage | 5V ±10%
| 2 | GND | Ground |
| 3 | RX | UART: Receiving pin for communication | TTL 5V and LVTTL 3.3V compatible
| | SDA | I2C: Serial data input / output | TTL 5V and LVTTL 3.3V compatible
| 4 | TX | UART: Transmission pin for communication | TTL 5V and LVTTL 3.3V compatible
| | SCL | I2C: Serial clock input | TTL 5V and LVTTL 3.3V compatible
| 5 | SEL | Interface select | Leave floating or pull to VDD to select UART
| | | | Pull to GND to select I2C
| 6 | NC | Do not connect |
2. Open the `exampleUsage` sample project within the Arduino IDE
File => Examples => Sensirion I2C SEN44 => exampleUsage
3. Click the `Upload` button in the Arduino IDE or
Sketch => Upload
4. When the upload process has finished, open the `Serial Monitor` or `Serial Plotter` via the `Tools` menu to observe
the measurement values. Note that the `Baud Rate` in the corresponding window has to be set to `115200 baud`.
# Contributing
**Contributions are welcome!**
We develop and test this driver using our company internal tools (version control, continuous integration, code review
etc.) and automatically synchronize the master branch with GitHub. But this doesn't mean that we don't respond to issues
or don't accept pull requests on GitHub. In fact, you're very welcome to open issues or create pull requests :)
This Sensirion library uses
[`clang-format`](https://releases.llvm.org/download.html) to standardize the formatting of all our `.cpp` and `.h`
files. Make sure your contributions are formatted accordingly:
The `-i` flag will apply the format changes to the files listed.
```bash
clang-format -i src/*.cpp src/*.h
```
Note that differences from this formatting will result in a failed build until they are fixed.
