+AMG8833
+=======
+
+.. highlight:: c++
+
+Introduction
+------------
+
+A library to communicate with the cheap `thermal sensor AMG8833 <https://mediap.industry.panasonic.eu/assets/imported/industrial.panasonic.com/cdbs/www-data/pdf/ADI8000/ADI8000C66.pdf>`_.
+
+Using
+----- 
+
+1. Add ``COMPONENT_DEPENDS += AMG8833`` to your application componenent.mk file.
+2. Add these lines to your application::
+
+	#include <Melopero_AMG8833.h>
+
+	namespace
+	{
+	  Melopero_AMG8833 sensor;
+
+	  // ...

+	{
+		Wire.begin();
+		sensor.initI2C();

+Temperature Matrix
+==================
+
+A simple demonstrating how to handle interrupts with the Melopero AMG8833 sensor.
+The sensor communicates through I2C. Connection scheme::
+
+	Microcontroller ----------- Melopero AMG8833
+		       3.3V ----------- VIN
+		       GND  ----------- GND
+		       SCL  ----------- SCL
+		       SDA  ----------- SDA
+	 a valid INT Pin----------- INT
