MEROSS MS420 Intelligent multifunctional flood sensor
Description
About this product
Smart multifunction water leak sensor Meross MS420 helps protect your home from the effects of water leaks, rain flooding and freezing of installations. Thanks to its large electrode surface, adjustable probe height and 1.5 m cable, it also monitors hard-to-reach places, e.g. the space under the washing machine or around pipes. The alarm sounds with an audible signal at 100 dB.
Sensitive leak detection
The large electrode surface can detect even small amounts of water, so a minor leak can be noticed quickly. The adjustable probe height lets you set the sensitivity: at a low setting the sensor reacts to small amounts of water, while a higher position reduces alarms from momentary dampness. The sensor also detects the absence of contact with water, so it can monitor the water level in aquariums, tanks or pet fountains.
Probe on a cable
The 1.5 m cable with probe lets you cover places such as the space under the washing machine or around pipes, without moving the whole sensor. The small probe fits into narrow gaps, for example behind furniture. The included adhesive tape helps attach it in the chosen spot.
Detection delay and alarm conditions
The option to set a detection delay reduces the number of false notifications after brief contact with water. You can also combine different conditions, e.g. the appearance of water and low temperature. In the event of danger, the device sounds a loud alarm at 100 dB.
Moisture-resistant housing
The IP65 housing protects against dust and water jets, so the sensor is suitable for places exposed to moisture. The operating temperature range from -20°C to 60°C lets you use it in various conditions.
Battery for years
Bluetooth BLE limits power consumption, and the replaceable CR123A battery lasts up to 4 years. The sensor can therefore be left in a hard-to-reach place without frequent power replacement.
