+# ScioSense ENS16x
+Arduino library for the ENS160 and ENS161 digital four channel MOX gas sensor with I2C interface from ScioSense
+
+## Introduction
+This project is an Arduino *library*. It implements a driver with examples for the ENS160 and ENS161.
+The ENS16x chip is a digital gas sensor for TVOC and eCO2 with an I2C interface.
+The driver in this Arduino library is based on the code supplied by *Sciosense*, the manufacturer of the chip.
+
+Note that the ENS16x requires a supply voltage of 1.71V .. 1.98V.
+The ENS16x also requires a IO voltage of 1.71V .. 3.6V.
+
+## Links
+The ENS16x is made by [Sciosense](http://www.sciosense.com).
+ - The datasheet of the ENS160 is available through the website. The datasheet of ENS161 is not yet released but can be provided on request
+
+## Prerequisites
+It is assumed that
+ - The Arduino IDE has been installed.
+   If not, refer to "Install the Arduino Desktop IDE" on the
+   [Arduino site](https://www.arduino.cc/en/Guide/HomePage).
+ - The library directory is at its default location.
+   For me, that is `C:\Users\sciosense\Documents\Arduino\libraries`.
+
+## Installation
+- Visit the project page for the Arduino ENS16x library.
+- Click the green button Clone or download on the right side.
+- From the pop-up choose Download ZIP.
+- In Arduino IDE, select Sketch > Include Library > Manage Libraries ... and browse to the just downloaded ZIP file.
+- When the IDE is ready this README.md should be located at e.g. `C:\Users\sciosense\Documents\Arduino\libraries\ScioSense_ENS16x\README.md`.
+
+## Build an example
+To build an example sketch
+ - (Re)start Arduino.
+ - Open File > Example > Examples from Custom Libraries > ENS16x > ENS16xbasic_normal
+ - Make sure Tools > Board lists the correct board.
+ - Select Sketch > Verify/Compile.
+
