+
+`msp430` directory contains microcontroller code for the sensor.
+Connect the wires from the water meters to the ground pin and
+pins P1.4 and P1.5 for cold and hot meters respectively. Internal
+pullup is used. To save power, modify the code to disable internal
+pullup, and use external pullup resistor of 5 - 10 MOhm. And
+probably disable VCLK in sleep mode.
+
+`linux` directory contains the code to be run on Linux host. It
+uses BlueZ infrastructure. You will need a BT 4.0 compatible
+hardware connected to the host.
