in numerous forms. But for the ZMPTIO1B voltage sensor, the setting has to be provided by the user through the trim potentiometer. The easiest way of implementing sensor calibration is to apply a correction polynomial to the output of the sensor to cater for the distortion in the system. The method used calibrating the ZMPT1O1B sensor which works based on electric field detection. In this the analog input to the sensor and its ADC output. This will eliminate the need for minimizing the output distortion in especially for power consumption measurement in power system. Hence there will be faster response by the system. The voltage sensor ZMPT101B is shown in Fig. 3.9. 1.Vec 2.0ut 3,.GND 4,GND 6.AC : Phase. -~@ Fig. 3.9 Voltage Sensor ZMPT101B ZMPT10JB voltage sensor module is a voltage sensor made from the It has high accuracy, good consistency for voltage and power measurement and it can measure up to 250V AC. It is simple to use and meter foradjusting the ADC output. The analysis n the input voltage and the ADC ZMPT101B voltage transformer. comes with : : . mes with a multi turn trim potentio is tha ~ ere that to find more accurate relationship betwee ADC output is adjusted using the trim pot to an 0 _ : +t ulput by regression analysis. The Ppropriate value against a reference input. 19 The VS acts as a small voltage transformer which is used to get readings depending on its turns ratio. The voltage sensor has op-o7 which is a kind of amplifier used to send signals to the ESP32. We have chosen this voltage sensor because of its accuracy and speed. We should have suitable resistors to step down the voltage and gives signal.The layout of VS is shown in Fig. 3.10 19 4-00, SCivcular needle pin | ° 195 "¥'Sane polarity | Fig. 3.10 Layout of VS The circuit of VS is shown in Fig. 3.11 and it also shows op-amp and other resistors. 20
