The project involves utilizing an Arduino microcontroller and a DHT11 sensor to measure and display real-time temperature and humidity data. The project aims to create a cost-effective and reliable ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
