Modbus RTU
E+E Elektronik EE671 - HVAC Miniature Air Flow Probe
E+E Elektronik
Measures air velocity and temperature for HVAC applications.
Overview
The E+E Elektronik EE671 is a compact air velocity probe for HVAC applications. This Modbus RTU template reads airflow speed (m/s) and temperature (°C) from the device using float32 registers. No writable controls are included.
Key readings
Airflow (m/s)
Temperature (°C)
Use cases
Monitor real-time air velocity in HVAC ducts from a centralized cloud dashboard.
Log duct temperature trends over time to verify air handling unit performance.
Create an alert when airflow drops below a minimum threshold, indicating a blocked filter or damper fault.
Compare supply and return air velocities across multiple zones in a commercial building.
Generate periodic airflow reports for facility managers or building compliance documentation.
Installation
1Wire the EE671 probe to the ModbusCloud gateway (MCG or MLP series) using a shielded RS-485 cable, connecting A, B, and GND terminals.
2Set the EE671 Modbus slave address using the configuration method described in the device manual, and note the address for gateway setup.
3Configure the ModbusCloud gateway serial port to 9600 baud, odd parity, and 1 stop bit to match the EE671 default communication settings.
4Import the E+E Elektronik EE671 template from the ModbusCloud template library and assign it to the correct gateway port and slave address.
5Verify that airflow (m/s) and temperature (°C) values appear on the ModbusCloud dashboard, and confirm readings match expected conditions in the duct.
