This Sensor will help you to monitor the main parameters of your swimming pool.
To avoid replacing the batteries so often, a rechargeable Li-Ion 16850 battery is charged by a small 5V, 100ma, 9x6cm solar panel on top of the case.
Readings are done on every 12min. 5V step-up is connected to D3 pin in order to activate the sensors only during reading cycle.
By using the nice Ceech board, some nice features are available:
(and some rocks for perfect balance) ;-)
