Sensor calibration is done so that the data acquisition system can get more accurate data. Calibration procedures are carried out by the team at Laboratory of Energy and Thermal Environmental Engineering, Department of Engineering Physics, ITS in October-November 2023. The calibration procedure includes sensor reading test for accuracy, precision, hysteresis, etc. Sensors that have high accuracy and met other criterion (as per spec) will be installed in the overall data acquisition system. Sensors that we calibrate are:
| Data Acquisition Module | ||
| Component | Data | Install Location |
| DHT 22 | Humidity | Floater |
| PZEM 17 | Voltage & Current | Power Cable |
| DS3231 | Time | Every Microcontroller |
Below is some documentation of the activities carried out by the team while calibrating the sensors.
