Sensor Calibration

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
ComponentDataInstall Location
DHT 22HumidityFloater
PZEM 17Voltage & CurrentPower Cable
DS3231TimeEvery Microcontroller

Below is some documentation of the activities carried out by the team while calibrating the sensors.
