      1. Data LoggerPCB Antenna was designed for 2G and 4G bands. Pattern and S Parameters were obtained with HFSS. The trace(coplanar waveguide) between the RF transceiver and the antenna was calculated and drawn with Altium Designer. Humidity, accelerometer, air quality, light and temperature sensors were selected and communication was established with the GSM module and I2C interface.2. Electromagnetic Flow Meter2.1 RF/Microwave Parts of Electromagnetic Flow MeterThis PCB consist of GSM, LoRa and Bluetooth antennas, as well as three RF transceiver modules. The traces (coplanar waveguide and microstrip) between RF transceivers and antennas were calculated and drawn with Altium Designer.2.2 MCU, Digital Communication and HMI parts of EMFThe STM32L0 series microcontroller was used based on the RS-485, Analog Outputs(4mA-20mA and 0V-5V), and HART requirements. The impedance of the RS-485 (Diff. coplanar waveguide) trace was calculated with Altium Designer. Capacitive touch pads were designed for HMI.3. USB-RS-485 ConverterThe isolated transceiver was selected. The push-pull converter was designed for the selected transceiver. The transformer driver and transformer were used according to the transceiver's requirements. The impedance of the RS-485 (Diff. coplanar waveguide) trace was calculated with Altium Designer.4. Vortex Flow MeterA differential mode and common mode filter were designed for the variable frequency sinusoidal wave from the sensor. The differential signal was converted to a single-ended signal using an instrumentation amplifier. The signal was amplified so that the microcontroller could interpret it. The circuit was simulated using LTSpice. Show less
