4.2 Wiring
The sensor transmitter uses an RS485 interface for communication and requires a 12V-36V DC power supply. Connect the wires according to the following specifications:
- Red Wire: Power supply (12-36V DC positive)
- Yellow Wire: RS485+ (Data A)
- White Wire: RS485- (Data B)
- Black Wire: Negative (Ground)

Ensure all connections are secure and properly insulated to prevent short circuits or damage.
5. Operating Principles
The Sorandy sensor transmitter converts environmental temperature and humidity into corresponding numerical data using an integrated digital sensor. This data is then processed by a full digital conditioning circuit and transmitted via the RS485 interface. The RS485 protocol allows for robust and long-distance communication, making it suitable for industrial applications.

7. Maintenance
To ensure optimal performance and longevity of your sensor transmitter, consider the following maintenance guidelines:
- Regular Cleaning: Periodically inspect the sensor tip for dust, debris, or moisture accumulation. Clean gently with a soft, dry cloth if necessary. Avoid using abrasive materials or harsh chemicals.
- Filter Inspection: The sensor features a removable anti-blocking design. Inspect the filter for any blockages and clean or replace it as needed to maintain accurate readings.
- Connection Check: Regularly verify that all wiring connections are secure and free from corrosion or damage.
- Environmental Monitoring: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent sensor damage.
8. Troubleshooting
If you encounter issues with your sensor transmitter, refer to the following common troubleshooting steps:
- No Power/No Reading:
- Check the power supply voltage (12V-36V DC) and ensure it is correctly connected to the red and black wires.
- Verify that the power source is active.
- Incorrect Readings:
- Ensure the sensor tip is clean and free from obstructions.
- Confirm the sensor is placed in an appropriate location, not affected by localized heat, cold, or moisture.
- Check for any physical damage to the sensor or cable.
- Communication Errors (RS485):
- Verify the RS485+ (Yellow) and RS485- (White) connections are correct and not swapped.
- Check for proper termination resistors in the RS485 network, if applicable.
- Ensure the communication parameters (baud rate, parity, data bits, stop bits) on your receiving device match the sensor's settings.
- Intermittent Readings:
- Inspect all wiring for loose connections or damage.
- Check for sources of electromagnetic interference (EMI) near the sensor or wiring.
