Product Description

The KREU-WTL-U526 Module is a versatile IoT sensor engineered for industrial automation, environmental monitoring, and smart agriculture applications. Featuring four configurable digital/analog inputs and two relay outputs, the WTL-U526 Wireless Transmitter seamlessly interfaces with sensors, actuators, and control modules via Wi-Fi, Bluetooth 5.0, and LoRaWAN protocols. Operating within a robust voltage range of 2.7-5.5V DC, it sustains reliable performance across extreme temperatures (-40°C to 85°C). The KREU U526 IoT Sensor excels with its ultra-low power consumption, enabling up to 3 years of operation using its integrated 5000mAh lithium battery. It achieves a wireless transmission range of 300 meters in open areas, though performance may degrade in dense environments. Compact and screen-free, this module prioritizes durability and adaptability, though external power backup is recommended for continuous high-load scenarios.
