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 [...]

LED Control Using IR Receiver - Practical Implementation

Controlling LED’s using IR Remote Control – Arduino Project

This article allows you to turn ON and OFF LED’s using a cheap IR remote control. Here we used an available IR Arduino library so it was pretty easy to decode the signals transmitted by the infrared remote. The LED’s which are connected to Arduino will be controlled by IR Transceiver module. IR Transmitter i.e., Remote transmits unique code to IR sensor wirelessly. IR sensor receives that signal and controls the LED’s which are connected to Arduino according to Code. Required ComponentsIR sensor Arduino Uno 4 [...]

Controlling of DC Motors using MPU5060

In this project, we are going to control the speed of 2 DC motors using the MPU6050. MPU6050 is an accelerometer and Gyro sensor. By moving the sensor in upward or downward direction, the speed of the motors will increase or decrease. By moving the sensor in upward direction, the speed of first motor will increase and the speed of other motor will decrease. Similarly, by moving the sensor in downward direction, the speed of first motor will increase and [...]
