ESP8266: Read DHT11 measurements

The objective of this post is to show how to connect the DHT11 sensor to an ESP8266 and write a simple program to measure temperature and humidity. We assume the use of the Arduino IDE for programming the ESP8266.

IoT: Temperature logger

The objective of this post is to explain the architecture of a simple temperature logger using the ESP8266 and a web server deployed on the cloud.

Laws of electronics: KCL

This post describes one of the basic laws of circuit analysis, more precisely KCL (Kirchhoff’s Current Law), which states that the the sum of the currents leaving and entering a node is zero.

Laws of electronics: KVL

This post describes one of the basic laws of circuit analysis, more precisely KVL (Kirchhoff’s Voltage Law), which states that the sum of all voltages in a closed loop of a circuit are equal to zero.
