Temperature Controlled Fan using Arduino In today's fast-paced world, convenience is key. Dealing with the temperature fluctuations in your living space can be quite a hassle. For those who live in regions where the afternoons can be sweltering hot and the nights chillingly cold, constantly adjusting your wall fan can be annoying. However, with a little bit of DIY ingenuity and the help of some electronic… |

How Does a LM35 Temperature Sensor Work and how to Interface it with Arduino? If you are looking for an inexpensive, accurate, easy-to-use temperature sensor, then LM35 is an excellent choice. It has an accuracy of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. It does not require any external trimming, although the main drawback of this sensor is that it outputs data in analog format, making it … |

A Simple Dynamic System for Monitoring of Heart Rate, Oxygen Level and Body Temperature We all saw how everyone started to panic during the onset of the pandemic, and it was because of the lack of solid information and the spread of fake news. And this is how people fall under the misconception and get confused about the symptoms of a disease. That is why we wanted to build a project that will allow people to check whether they are COVID… |

ESP32 based Temperature Sensitive Smart Fan Regulator Do you feel disturbed when you need to adjust the temperature? The wait is over, the solution is here! We often feel uncomfortable while sleeping due to certain changes in room temperature, but we don’t want to get up from sleep and regulate fan/AC due to lethargy. This hampers our sleep and may put a negative effect on our health. We will use Arduino… |

AJAX with ESP8266: Dynamic Web Page Update Without Reloading In many IoT applications, there are situations where the sensor data needs to monitor continuously, and the simplest way to do that is by enabling an ESP8266 webserver which serves an HTML webpage; but the problem with this methodology is that the web browser needs to be refreshed at a certain time interval to get an updated sensor data. This is not only… |

LM35 Temperature Sensor Not Working? - Here is what you should do… For one of our projects, we tried to Interface LM35 Temperature Sensor with Arduino but were unable to do so. Yes, what seemed like an easy task became a whole day's effort. We initially assumed the sensor was defective, but after testing about 15 sensors, we saw the same issue over and over again; all of these sensors came from the same lot of 85 sensors we had in… |

Frequency Compensation of Op-amp and why it is important in your Op-Amp Circuits Operational Amplifiers or Op-Amps are considered the workhorse of Analog Electronic Designs. Back from the Analog computers era, Op-Amps have been used for mathematical operations with analog voltages, hence the name operational amplifier. To date, Op-Amps are extensively used for voltage comparison, differentiation, integration, summation and many other things. Needless to… |

IoT Digital Thermometer using NodeMCU and LM35 In previous Getting start with NodeMCU tutorial, we saw What is NodeMCU and how we can program it using Arduino IDE. As you know NodeMCU has Wi-Fi chip inside so, it can also connect to internet. It is very useful to build IoT Projects. We previously used ThingSpeak with Arduino to make IoT thermometer, but here we will create our own webpage to display temperature.… |

Digital Thermometer using LM35 and PIC Microcontroller In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16x2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any external calibration. The output voltage is proportional to Celsius temperature scale and changes by 10mV… |

Digital Thermometer using LM35 and 8051 Microcontroller Sometimes people find it difficult to read temperature from analog thermometer because of fluctuations. So here we are going to build a simple Digital thermometer using 8051 microcontroller in which LM35 sensor is used for measuring the temperature. We have also used LM35 to build digital thermometer using Arduino, NodeMCU, PIC, Raspberry Pi and other microcontrollers.… |

Temperature Controlled Automatic Switch Previously we have built Temperature controlled LEDs Circuit, in which two LEDs were glowing according to the temperature. Now we are enhancing that circuit by using a Relay, and now we are going to Control Home AC appliances according to Temperature. This circuit will serve as automatic light switch which will trigger if temperature goes beyond a particular level (50 Degree… |
