Kemo M158 Water Sensor Relay Switch Module 9-12V DC - Kemo M158
This module has a very sensitive input for a pair of probes. When the 2 probes come into contact with water a relay switches on which can be used to control sirens lights pumps etc.
The water sensors use an extremely low voltage in order to prevent the otherwise usual oxidisation through galvanic currents.
