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 ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

This IoT-enabled system continuously tracks a bedridden patient’s vital signs (ECG waveform, heart rate, and body temperature) from anywhere in the world. By combining a microcontroller (Arduino) with ...

This project demonstrates the development of an energy-efficient system to regulate a fan's speed automatically based on room temperature. By integrating an Arduino Uno microcontroller, a DHT11 ...

Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI ...

To make a remote temperature sensor with the LTC2970, run two different currents (ILOW and IHIGH) through the transistor and measure VBE at both currents (VBE_LOW and VBE_HIGH). The difference between ...
