Lora SX1276/7/8/9 Library for STM32F103C in Keil
Hi guys this article is to discuss the Lora module interfacing with the STM32F blue pill board. The driver is implemented to transmit and receive the data between two devices in Keil IDE using the HAL driver. This library mostly focuses on the Lora mode and uses SPI communication. In Lora mode, we can access…
How to monitor Sensor values in Blynk App using Raspberry Pi
Hi guys, in this article we will discuss how to monitor the DHT sensor values in the Blynk application. For this we should have an account in the Blynk app, we can signup into Blynk either by Gmail or Facebook. After signup create a project with text labels, and we get an auth key to…
How to display DHT sensor values on GUI application in raspberry pi
Hi guys, this article is to read the DHT sensor values temperature and humidity, these values are displayed on the PyQt5 GUI application. This GUI is designed in Qt designer (see below image) and converted to the .py file. DHT11 is a temperature and humidity sensor. This sensor has 3 pins (VCC, OUT, and GND).…
Posting Sensor Values to the Server using WiFi Module with Arduino Uno
Introduction: In this tutorial, I am going to explain about sending sensor values to the thing speak server. ThingSpeak is an open-source server, so users just need to sign up with your email id. After sign up creates a new channel to get an API key, this key is unique for every channel. By using…
