“Introduction The SparkFun SAMD21 Pro RF is the fated meeting of a SAMD21 and a long-range RFM95W LoRa®-enabled radio. The outcome is a compact, blazing fast microcontroller with excellent point to point data transmission in the 915MHz ISM radio …
“This project involves the implementation of a system responsible for collecting data about the electric energy generated by an off grid photovoltaic system and transmitting them to an LED panel through wireless, using two LoRa 32 WiFi controllers, responsible for …
“In this tutorial we’ll explore the basic principles of LoRa, and how it can be used with the ESP32 for IoT projects using the Arduino IDE. To get you started, we’ll also show you how to create a …
“Small, cheap, low-powered sensors are still a challenge to make. LoRa-Tooth uses $6 BLE modules to make untethered sensors with long range. Today, we have a lot of tools for building wireless devices. The ESP8266 is probably on the top …
“Can you imagine a 1W Radio LoRa that is 10 times more powerful than the traditional 0.1W ones? Well today Ill introduce you to the E44-TTL-1W module, which is exactly this. This model has a transistor in …
“As this is a popular subject among those following my posts, I decided to talk about LoRa today. However, Im going to discuss the subject with some new elements: this time without using the ESP32, but the STM32 instead. I …
“This is a wireless sensors project that involves using LoRa and WiFi to extend the range of BLE sensors. In addition to building sensors and gateways, I also want to integrate the data into nice looking visualizations using open source …
“QuadMeUp Crossbow is a DIY project that gives 5km (at least) of RC link for UAV (airplanes and drones) for a price below $40. I uses SX1278 (LoRa 868MHz/915MHz) compatible (like HopeRF RFM95W) radio modules connected to Arduino compatible …
“Following suggestions from my YouTube channels followers, we will talk about the ESP32 LoRa again today. However, this time well discuss sending and receiving data by the same device. In this situation, an ESP32 LoRa, the Master, will send a …
“Considering that it offers a solution to many current problems, today I am continuing the discussion concerning the ESP32 LORA, a marvel for this Internet of Things world. In this article, I deal again with safety when discussing an infrared …
