| Product Introduction
The winchen sensor WCIS300 series wireless inclinometer is a new-generation intelligent sensor integrating a high-accuracy MEMS tilt measuring unit and a low-power wireless communication module, capable of outputting the tilt angle of an object in real time on a single or dual axis. The device sends angle data directly to the cloud or a local gateway via LoRa, NB-IoT, 4G and other means, enabling remote unattended monitoring. Its IP67 protection design allows long-term deployment in the field, underwater or in high-dust environments, and it supports multi-device networking and abnormal-condition alarms.
| Features
1. Ultra-low power: uses an ultra-low-power MCU and adaptive sensing strategy, maximum power consumption 0.5w;
2. High accuracy and high stability: core MEMS device, accuracy up to 0.05°, resolution 0.001°, automatic temperature compensation across the full temperature range, long-term zero bias better than 0.1°/year;
3. Rich wireless protocols: supports LoRa self-organizing network (typical transmission 3-8 km) and NB-IoT/4G public network direct cloud connection, selectable by scenario;
4. Sturdy protection and easy installation: IP67 protection rating, salt-spray resistant, vibration and shock resistant, supports custom zero point;
5. Compatible with various cloud platforms: can connect to the winchen cloud platform or third-party systems, supporting real-time curves, historical reports and SMS alarms;
