Sensor Monitoring Using LoRa & Arduino

There are various sensor monitoring methods are available some of them using IoT and others using offline protocols like Bluetooth and BLE. But the offline method doesn’t offer a good range and online methods are expensive and very compilated. Today, we are going to make a simple sensor monitoring system using LoRa (long range radio)….

NTC v/s PTC Difference And Applications

NTC and PTC are known as thermistors, which can be further known as temperature-controlled resistance. Now something is related to resistance but how it works and which type of circuits can be designed using these components. Let’s know the working concept and then we will use them practically. The value of these thermistors is not…
