[elecena] Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - zmiany ceny 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. * Kemo type M158 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 11.88 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2024-11-11 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 10.09 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2025-03-23 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 9.78 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2025-05-22 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 11.48 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2025-06-29 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 11.88 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2025-07-18 Kemo M158 Water Sensor Relay Switch Module, 9-12VDC - 11.98 GBP https://elecena.pl/product/27220165/kemo-m158-water-sensor-relay-switch-module-9-12vdc 2025-08-28
