Home monitoring with ESP32. Part II — towards a more accurate temperature with LM35 sensor

My system: ESP32 + LM35, MQTT +Influxdb + Grafana now allows me to log the temperature, with one problem: the readout is about 5–6 degrees lower than the reads from a reference thermometer. I am going to show you how I set out to fix that.

Capture the fluctuations of temperature from 4 am to 4 pm.
