Energy Monitoring System Calibration: Linear Regression Approach for Sensor Accuracy
A practical look at calibrating DHT11 sensors using linear regression to improve temperature and humidity accuracy for energy monitoring systems.
Danke Hidayat
I build software that has to survive real sensors, real networks, and real people.
Computer engineer in Bandung. Day job at PT. Labdha Teknika Nusantara: IoT, full-stack work, and the ops that keep dashboards honest. At night I write stories, study Japanese, and play too many games.
