Surface acoustic wave (SAW) filters may sound exotic, but they are everyday workhorses in wireless front-ends. Compact, cost-effective, and reliable, they shape signals with precision while keeping ...

This project detailed how to use multiples ESP32Cam (solar charged) to capture few times by day a picture and send them remotely to a touch display with 2 RF modules low power The background of this ...

Abstract: This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable ...

This project covers a complete (Home Assistant) smart home solution for single family houses and apartment buildings facing the primarily requirement of replacing the existing high voltage switching ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

At embedded world, on the DigiKey booth, Lucy Barnard speaks with Marta Barbero at Arduino, about the new Arduino product announcement.

VENTUNO Q eliminates multi-device complexity because it delivers synchronized perception, decision, and action on a single board. The main processor runs Ubuntu and Linux Debian with upstream support, ...

The HC-12 has a great range for 433MHz but the downside is that the module can only communicate with another HC-12. Also the price for these modules are very similar to ESP8266 and LoRa devices at ...

Abstract: To meet the increasing need of wireless communication, radio frequency (RF) modules are commonly included in the design of flexible hybrid electronics (FHE). The reliability of printed ...
