Once the meter is read, the usage data will be zeroed out to start a new measuring cycle. tuya_get_measure_rslt Get the result of the production test. tuya_get_calibration_para Get the calibration factors including voltage, current, power, and consumption. tuya_clear_calibration_date Clear ...
A breadboard is used first to build the meter circuit from the selected components: Arduino Uno, LoRa, 12 V battery, sensors, resistors, potentiometer, LCD, LED, bulbs, and jumper wires. In addition, we used Arduino IDE software to write code and upload it to the board. First, the ...
The meter communicates with a PC through an RS-232 serial port, which is hidden inside the meter case. To access the serial port, open the meter case. (See the Connection communication/JTAG cables section below.) Be sure to power off the AC supply before proceeding. Note that the MAXQ318...

Figure 1. Complete circuit diagram of the smart energy meter. 3. Results and Discussion Inside the smart energy meter there are two sensors connected, which interact with the incoming power line or source. One potential transformer is connected on the incoming side to measure the line voltages...
These solutions optimize the design of the sampling circuit to improve the sampling accuracy, but they only achieve simple comparisons between the sampled energy measurement from the control terminal and the measured value of the energy meter. As a result, the issue of inadequate traceability of ...
