+# Internal Status 
+
+This package contains a library which allows us to get current and voltage values from the Power Sense Module (PSM), and a ros node which publishes this data to the whole ROS environment.
+
+## PSM lib
+
+The ASV as a PSM. It takes voltage and current data going into internal electrical instruments on board. This library is a driver, which allows us to get the voltage (in V) and current (in A) values from PSM through I2C.
+The I2C address is 0X69.
+* Typical values for voltage: around 21V
+* Typical values for current: around 0.6A
+
+
+## PSM node
+
+This ros node just publishes the current and voltage data we get from the lib to the entire ROS environment.
+### Publishes to 
+* /asv/power_sense_module/current for the current data [A]
+* /asv/power_sense_module/voltage for the voltage data [V]
