Product Description

The W421 sensor module is a multi-functional device integrating proximity detection and temperature monitoring. Designed for industrial automation, HVAC, and robotics, it features 2 digital inputs, 3 programmable outputs, and direct connectivity to 4 peripheral modules via UART or I2C. Operating at 3.3-5V DC with a -20°C to +85°C range, the W421 proximity detector offers a 5 cm sensing distance using infrared technology, while its embedded W421 temperature switch activates at configurable thresholds (±1°C accuracy). The module excels in compact size (no integrated screen) and low energy consumption, supporting optional 2000mAh battery backups for mobile deployments. However, its non-shielded design may require external EMI protection in high-noise environments. Robust construction ensures reliability in machinery and production-line applications where space and precision are critical.
