This project demonstrates the design and programming of an electronic circuit using the LM35 analog temperature sensor with Arduino. The circuit reads temperature values from the sensor and displays ...

This project collects temperature and humidity data using a DHT22 sensor connected to an Arduino. Data is sent via a Python bridge to a Flask backend, which validates and stores it in MongoDB. The ...

This system demonstrates water level and temperature monitoring on a 10.92cm (4.3-inch) TFT LCD using graphics and colour-changing animation of water filling a tank, along with a rising temperature ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Primarily poised for pool and spa applications, the AquaSense water-temperature sensor promises ease of installation and a fast temperature response time. Housed in a rugged, molded shell, it is ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
