Automatic AC Temperature Controller using Arduino, DHT11 and IR Blaster IoT Weather Station using NodeMCU: Monitoring Humidity, Temperature and Pressure over Internet DHT22 Temperature and Humidity Sensor Module The DHT22 module has a total of 3 pins. And the DHT22 bare bone sensor has 4 pins....
We will use an Arduino library for the BH1750 light sensor. Go to this link and download the Arduino library. This library is provided by claws on Github. One of the major pros of using this library is that we do not have to worry about the internals of module and configuration settings...
In this article we are going to explain about interfacing Rain Sensor withArduino. The rain sensor module is an easy tool for rain detection. It operates as a switch when raindrop falls through the raining board and also it measures rainfall intensity. The module features, a rain sensing boar...
Arduino with Transistors For the first couple of experiments, we will use the TIP120 power Darlington BJT. You can substitute a BJT with similar specifications if you don’t have a TIP120. I’ll be using 6-volt batteries and loads for my experiments, but you can use any DC power source...
A note on Sensor Libraries Currently I use the Sparkfun library; but there is also one from Pololu:https://github.com/pololu/vl53l1x-arduino&https://www.pololu.com/product/3415/resources Both of these are 'light' libs designed for ATMega arduinos (eg limited RAM, etc). The Official ST...
