FREEVOLVE housEvolve water presence sensor is an accessory for the housEvolve water detector module (not included). Add up to 6 sensors for each water detector module to allow for affected area mapping of water leaks.
When used in conjunction with the housEvolve remote monitoring system (not included), any housEvolve water sensor that gets wet can activate the housEvolve unit and if the automatic water valve (not included) is installed, the water will be shut off automatically.
