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

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

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 ...

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 ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...

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 ...

We’ve all been there. Your current project has hit a wall, or the next step will take days to complete, and you need something to do in the meantime. So you start a project that you envision will fit ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...
