EM300-MLD-868M: environmental water leak monitoring sensor ### Minimize water losses The EM300-MLD membrane leak detection sensor, the latest addition to our water leak detection product line, features a 40 cm x 40 cm detection membrane, ensuring reliable water leak monitoring for residential and commercial applications. ### Protect every inch with the membrane leak sensor Unlike rope or spot leak sensors, the EM300-MLD membrane leak detection sensor offers a 40 cm x 40 cm membrane, allowing it to cover larger areas and effectively detect water leaks. ### Meet needs with a customized membrane The EM300-MLD membrane can be cut vertically to fit specific requirements. Additionally, it supports large size customization (contact Milesight). ### Versatile protection for every space Designed to meet various needs, the EM300-MLD is suitable for both residential and commercial environments. Whether placed under appliances like washing machines and refrigerators, or used to monitor roofs and ceilings for potential leaks, this sensor offers comprehensive coverage and ensures timely notifications to prevent costly damage. ### Robust data storage and retransmission The EM300-MLD locally stores up to 1,000 sets of historical data records. With support for data retrieval and retransmission, it ensures data integrity even in the event of occasional network outages. ### Complete solution for water leaks Milesight offers both zone and spot leak detection options to meet various needs. Whether you need coverage for larger areas or pinpoint accuracy, we have the right products for you. ### Ultra-low power consumption The EM300-MLD has an operating life of up to 10 years with a single battery, with the possibility to extend it further using two batteries. ### LoRaWAN based Signal penetration: data transmission range up to 2 km in urban areas and 15 km in rural areas. High compatibility: it is compatible with standard LoRaWAN® gateways and network servers. ### Milesight D2D Communication The Milesight D2D (Device to Device) communication protocol with LoRa® enables communication between different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.  ### Data management in Milesight IoT Cloud Data visualization dashboard: All data at a glance Automatic triggers: Interactive collaboration with Milesight IoT sensors to achieve scene-based automation Periodic reports and real-time alerts: Data-driven insights Android and iOS App: Device management at your fingertips ### NFC Configuration Power on/off and device configuration via NFC technology from mobile phone or PC   ## Features - Sensitive leak detection with membrane - IP67 waterproof rating for enhanced durability - Data storage and retransmission - LoRaWAN® connectivity for reliable communication - Milesight D2D communication - Extended performance: 10-year battery life ## Technical Specifications - LoRaWAN Technology - Frequency CN470/IN865/RU864/EU868/US915/AU915/KR920/AS923 - Operating Temperature - -30°C to + 70°C - Accuracy 0°C to + 70°C (+/- 0.3°C), -30°C to 0°C (+/- 0.6°C) - Humidity - Range 0% to 100% RH - Accuracy 10% to 90% RH (+/- 3%), below 10% and above 90% RH (+/- 5%) - Power Supply 1 × 4000 mAh ER18505 Li-SOCL2 (extendable to 2 batteries) - Battery Life* 10 years (10 minute interval + 24 activations per day) - Operating Temperature -30°C to +70°C - Relative Humidity 0% to 100% (non-condensing) - Ingress Protection IP67 - Dimensions 105.6 × 85.3 × 27 mm (4.16 × 3.36 × 1.06 inches) - Installation Wall mounting - Wireless Transmission - Technology LoRaWAN®, Milesight D2D - Frequency CN470/IN865/RU864/EU868/US915/AU915/KR920/AS923-1&2&3&4 - Tx Power 16dBm (868 MHz)/20dBm (915 MHz)/19dBm (470 MHz) - Sensitivity -137dBm @300bps - Mode OTAA/ABP Class A - Leak Detection - Liquid Type Conductive liquid - Activation Support 400 × 400 × 0.25 mm Printed leak detection film - (Dimensions can be customized) - Activation Condition When the detection film comes into contact with conductive liquid - Operation - NFC power on/off, power button (internal) - Configuration NFC configuration via mobile app - Advanced Features Milesight D2D controller, data storage, data retransmission - Physical Features - Cable Length 1000 mm (customizable) - Power Supply 1 ER18505 Li-SOCL2 4000 mAh battery (extendable to 2 batteries) - Battery Life* Up to 10 years (one hour of leakage per day, 25°C) - Operating Temperature -30°C~70°C - Relative Humidity 0% to 95% (non-condensing) - Color and Material White flame, ABS + PC (retardant) - Protection IP67 - Dimensions 105.6 × 85.3 × 27 mm (4.16 × 3.36 × 1.06 inches) - Installation Wall mounting with screws, 3M tape mounting, cable tie mounting VIDEO_ID --- Source: https://shop.marcomweb.it/en/lorawan/lorawan-environmental-water-leak-monitoring-sensor MARCOM S.r.l. — a trusted supplier for industrial automation and building automation.
