-# BlueRobotics_TSYS01_Library
-Arduino library for the TSYS01 temperature sensor.
+The sensor is the Measurement Specialties TSYS01, It comes standard with a 4-pin DF13 connector and compatible with most DroneCode compatible boards including the APM2.6, PixHawk, and others.
+
+## Features
+
+* ±0.1°C Accuracy
+* Standard DF13 connector for connection to DroneCode boards such as APM, PixHawk, Navio2, etc.
+* Sealed in a bulkhead penetrator for easy installation into any 10mm hole
+
+## Compatibility
+
+The Celsius sensor is compatible with any device with 3.3V I<sup>2</sup>C logic. When using with a 5V device, such as an Arduino Uno, it is necessary to use a logic level converter.
+
+##Configuration
+
+The sensor is mounted on a PCB that extends into the water and is sealed from water with a thick layer of thermally conductive epoxy. This mounting method minimizes heat capacitance and ensures a fast time-response.
+
+##Ratings
+
+For further information please see the [TSYS01 Data Sheet](http://meas-spec.com/downloads/TSYS01_Digital_Temperature_Sensor.pdf).
