DHT temperature and humidity sensors, are very basic and slow, but are great for hobbyists who want to do some basic data logging. Each DHT is made of two parts: Capacitive Humidity Sensor and Thermistor. There is also a very basic chip inside that does some analog to digital conversion […]

In this tutorial, we will show you how to build a low cost thermometer, using Arduino & DS18B20 waterproof version (Digital Temperature Sensor) Step 1: Items you need to have Arduino UNO (or other Arduino Models) DS18B20 Waterproof Resistor 4.7KOhm (Preferably 1/2Watt). You can check the Watt availability for 4.7KOhm […]
Step 1: Items you need to buy 1x Arduino UNO 1x Color Sensor 1x Breadboard 1x RGB Led 3x Resistors – 220E Step 2: Connections Connect the following pins together properly: Color Sensor: S0 <-> PIN 3 S1 <-> PIN 4 S2 <-> PIN 5 S3 <-> PIN 6 Out […]
This Sensor KY-037 is easy to use, cheap and can be used in different applications. It has two outputs: AO, analog output, real-time output voltage signal of the microphone. DO, when the sound intensity reaches a certain threshold, the output high and low signal. The threshold-sensitivity can be adjusted […]
