The setup allows periodic readings from a DHT11 temperature and humidity sensor using an Arduino Uno development board and an Ethernet shield. Sensor readings (temperature and humidity) as well as ...

Code to read temperature from an analog sensor connected to pin A0 on the Arduino Uno. The analog value is converted to degrees Celsius using the map() function. The temperature is displayed on the ...

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 ...

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 ...

We build this Arduino-based Digital Thermometer for temperature measurement applications. Thermometers have been useful for temperature measurement for a long time. A digital thermometer is an ...

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 ...

If you are a maker or an electronics enthusiast, then you must be familiar with the Arduino platform and their boards. As we know, the Arduino platform made it easier for makers like us to make our ...

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 ...
