Water Leakage sensor
KS51- Water Leakage Sensor of LoRaWAN
KS51 is a wireless water immersion sensor, which monitors whether there is a water immersion event in the area monitored by the probe in real time through the sensor. When a water immersion event occurs, the alarm information is triggered and uploaded to the application platform through LoRa signal.
KS51 periodically sends heartbeat information to ensure that the application platform monitors the running status of the device in real time. The default configuration period is 3 hours. The user can set the sampling period and the heartbeat period through the palm machine or the management platform.
Supports LoRaWAN and LinkWAN protocols, IP65 protection level.
KS51 through real-time monitoring of flooding events, and alarm, the first time to inform the management of the flooding site for timely treatment, for storage, warehouse, factory and other events to protect, to avoid the loss of goods or equipment due to flooding events.
KS51 based on LoRa ® Wireless technology, supports standard LoRaWAN ® Networking communication has the characteristics of long communication distance and low power consumption. The product has 4 built-in 2700 mA-hour large-capacity lithium battery, which can last for more than 8 years.
Product support with ManThink/3rd party LoRaWAN ® The gateway is combined with the ThinkLink/Chirp stack/TTN third-party Internet of Things platform to realize point-type and rope-type interfaces. KS51 has a high protection level of IP65, which can be widely applied to the management requirements of smart industries, smart buildings and other scenarios.
