“…Due to the neutralization process's sensitivity, flow measurement accuracy is vital. Therefore, procedures to calibrate the sensor are required to ensure that the sensor functions correctly [26][27][28]. The sensor calibration is carried out volumetrically by operating a pump between 5-12V DC to supply known reference volumes (500 ml and 2000 ml) and acquiring sensor rotation data.…”

Batik production in home industries needs support wastewater treatment in a limited space. Therefore, a modular-type, lab-scale wastewater treatment plant (WWTP) with a capacity of 87.75 liters and a dimension of 1.5 m × 0.75 m × 1 m has been constructed. The WWTP combines three significant processes: equalization, neutralization, and adsorption. This study focuses on the monitoring systems for the pH neutralization process. The system uses four microprocessors in a Master/Slave architecture and the I2C protocols for data communication between processors. The measuring instruments include pH, temperature, turbidity, and flow rate sensors. The actuators consist of submersible and peristaltic pumps. The operating range of pH, temperature, turbidity, and flow rate sensors are 0–14, 25–81.44℃, 0–3000 NTU, and 6.49–20.84 ml/s respectively. The pumps work in Pulse Width Modulation (PWM) mode with an operating range of 125–225 PWM. All sensors and actuators operate linearly within the operating range with a correlation coefficient of 0.97–1.
