SKU: SEN-000273-915
MPN: CS1010-UL-US9HT-00


The CS1010 is a long-range, low power water leak detection sensor supporting LoRaWAN protocol. The device provides configurable notifications or regular reported statistics. Early detection can mitigate costly repairs and provide peace of mind.

The device can be placed under water tank, water heater, sinks, washing machine, and in the basement. There are two pairs sensing probes at bottom and one pair at top of the base unit. A leak is detected when liquid contacts any pair of the sensing probes.

The CS1010 is powered by two AAA batteries and providing 5+ years of operation in normal conditions. Batteries can be easily replaced.

The device can be configured to provide leak detection/dry up/timeout alarms, and /or provide regarding event counts, event total and average durations. The CS1010 has temperature monitoring and alarm functions and battery status notifications.
