Product Description

The KREU-WTL-U522 module is a robust WTL-U522 wireless sensor designed for industrial IoT applications. Part of the KREU U522 Series devices, it features 4 digital inputs, 2 analog outputs, and supports direct connectivity with up to 8 external modules via LoRa, Wi-Fi, or ZigBee interfaces. Operating within a wide voltage range of 5-24V DC and an extended temperature tolerance of -20°C to 60°C, it excels in harsh environments like manufacturing plants, agriculture, and infrastructure monitoring. With a built-in 5000mAh rechargeable battery, it delivers 12+ months of continuous operation. The compact 2.4-inch display enables real-time data visualization, while its 100-meter wireless detection range ensures reliable remote monitoring. Key strengths include ultra-low power consumption and IP67 protection, though its LoRa bandwidth limitations may affect high-frequency data transmission. This sensor solution prioritizes scalability and environmental resilience for automated systems.
