This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

The Aqara Temperature and Humidity Sensor is a low-cost, simple, yet useful device that can enhance your HomeKit setup significantly. Here’s why you might want to install one in every room.

This project is designed to implement a smart home system using the ATmega32 microcontroller, sensors (LM35, LDR, Flame sensor), an LCD display, and a PWM-controlled motor. The system automates ...

Core is a very small, light sensor made from plastic. At just 12g is a device that once on, is easy to ignore and forget about. Core provides some adhesive patches so you can apply it directly to ...

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

Arduino-based Digital Thermometer – Circuit and Working The circuit diagram of the thermometer is shown in Fig. 2. The thermometer is built around an Arduino board (BOARD1), a temperature sensor LM35 ...

Spread the loveSchematic drawing software for Arduino, Raspberry Pi, and other Single Board Computers (SBCs) is essential to developing electronics projects. When it comes to creating circuits on a ...

The video indicates that the temperature sensor is the white circle. The 91mobiles report says the sensor is an infrared thermometer and similar to what most contactless thermometers use.

If we are looking at the 4-pin sensor the extra pin is a NC pin, and it has no functions. The pin diagram of both the module and the sensor is shown below. DHT22 Module Pinout The diagram below shows ...
