+# Arduino Adafruit HTU21D(D) library for Mongoose OS
+
+This is a port of the [Adafruit Arduino driver for the HTU21D(F) sensor](https://github.com/adafruit/Adafruit_HTU21DF_Library) ported to run on the [Mongoose OS ecosystem](https://mongoose-os.com/docs/reference/api.html).
+
+Usage is extremely simple....
+
+in _**mos.yml**_, add to **libs:** section,
+
+`  - origin: https://github.com/pedalPusher68/arduino-adafruit-htu21df`
+
+in your _**init.js**_, add something like the following,
+
+```javascript
+load('api_arduino_htu21df.js');
+```
+
+and
+
+```javascript
+// Initialize Adafruit_HTU21DF library
+let htu = Adafruit_HTU21DF.create();
+htu.begin();
+let htuGetData = function () {
+    print('HTU21D:  T: ', htu.readTemperature() ,'C     RH: ', htu.readHumidity(), '%');
+};
+let htuTimer = Timer.set(10000 /* milliseconds */, true /* repeat */, htuGetData, null);
+```
+
+to use the library.
+
+Enjoy!
