Interfacing DHT11 Sensor with ESP8266 - Practical Implementation

Interfacing DHT11 Sensor with ESP8266

In this article, I am going to explain about interfacing of DHT11 sensor with ESP8266. For that we have to make only 3 connections between the DHT11 sensor and ESP8266. For the working demonstration we will be programing ESP8266 as a web server for displaying temperature and humidity in a web browser as per request. Components RequiredESP8266 DHT11 Sensor USB Cable Connecting WiresHardware Circuit Diagram Interfacing DHT11 Sensor with ESP8266 – Circuit Diagram ConnectionsDHT11 sensor (+) pin will be connected to 3.3V DHT11 sensor (-) pin will be connected [...]

IoT Temperature Data Logger Using ESP8266 and LM35

IoT Temperature Data Logger Using ESP8266 and LM35

In this project, we are going to log and monitor temperature data over internet using ThingSpeak IoT server. And we can view the logged data and graph over time in their website. It is made using ESP8266 WiFi module and LM35 temperature sensor. ESP8266 WiFi chip reads the current temperature from LM35 using ADC and sends it to ThingSpeak server for live monitoring from anywhere in the world. Components RequiredESP8266 LM35 Breadboard Connecting WiresHardware Circuit Diagram LM 35 with ESP8266 – Circuit Diagram ConnectionsConnect 3.3V pin of ESP8266 [...]

Interfacing Moisture Sensor with Arduino

Interfacing Soil Moisture Sensor with Arduino

Introduction In this article, we are going to interface a Soil Moisture Sensor with Arduino Uno. We will measure the moisture content of soil in pot or farming field and by using this we can pour water into field based on preset values. This sensor measures the volumetric content of water inside the soil (based on resistance/conductivity) and gives the moisture level as output. The sensor is equipped with both analog and digital output, so it can be used in both [...]

Interfacing Rain Sensor with Arduino

In this article we are going to explain about interfacing Rain Sensor with Arduino. The rain sensor module is an easy tool for rain detection. It operates as a switch when raindrop falls through the raining board and also it measures rainfall intensity. The module features, a rain sensing board and the control board that is separate for more convenience, power indicator LED and an adjustable sensitivity though a potentiometer. Rain Sensor Module Raindrop sensor is basically a board on which [...]
