Product Description

The WHDM03 sensor module is a versatile device integrating the functionalities of a WHDM03 digital hygrometer and WHDM03 moisture detector, designed for precise environmental monitoring. It features 3 analog inputs, 2 digital outputs, and supports direct connections with up to 4 auxiliary modules via RS485 or Bluetooth interfaces. Operating within a wide voltage range of 8-30V DC and a temperature span of -20°C to 60°C, it is ideal for agriculture, pharmaceuticals, and HVAC systems. Key advantages include high accuracy (±1.5% RH), a long-lasting 5000mAh battery, and a 2.4-inch LCD for real-time data display. The module offers a detection range of up to 30 meters but may have limitations in extreme humidity conditions. Its compact design ensures easy deployment in confined spaces.
