Frequently Asked Questions

What is the communication protocol of the AW5485 module?

The AW5485 transmitter uses the RS485 physical layer with the Modbus RTU protocol. This industrial-standard interface allows for reliable, multi-drop communication over long distances, making it suitable for integration into PLCs, SCADA systems, and building management networks.

What is the power supply requirement for this sensor?

The module requires a 12V DC power supply and has a typical current consumption of ≤50 mA. Ensure your power source is stable and properly regulated to maintain the sensor's specified accuracy and long-term performance.

What is the measurement accuracy and sampling rate?

The sensor provides typical accuracies of ±0.5°C for temperature and ±3% RH for humidity. It has a resolution of 0.1 units and performs a measurement update (sampling period) every 2.5 seconds, providing near real-time environmental data.

Are there any environmental restrictions for installation?

For optimal accuracy and stability, avoid installing the sensor close to direct heat or cold sources, in direct sunlight, or in environments with persistent condensation, water mist, or corrosive gases. These conditions can affect sensor readings and long-term reliability.
