Siglent SHA800A analyzers combine the capabilities of a Spectrum Analyzer, a Vector Network Analyzer, and a Cable/Antenna Tester all in one intuitive handheld package.  With a frequency range up to 7.5 GHz, these analyzers deliver reliable automatic measurements and multiple modes of...

The project presented here is a low-cost solution to control the speed and direction of a high-power brushed DC motor using RC (Radio Remote Control) transmitter. This is an Arduino-compatible board, consisting of an Atmega328 chip, 2 x Relay for motor direction control, MOSFET for...

The SparkFun LoRaSerial Kit is a great way to transmit data over LoRa, providing you with a range far greater than that of WiFi or Bluetooth®. We've been able to successfully transmit data over a 9mi (15km) line-of-sight using two LoRaSerial radios with a larger 5.8dBi antenna on the...

While Matter, Bluetooth, Zigbee, and Zwave may get all the press these days, 433 MHz was the simple yet reliable technology that our sensors and devices relied on before they became popular. Given the wide range of applications for the 433 MHz, generalizations regarding the technology are...

Recently, LILYGO introduced a compact ESP32-S3 gadget that features a Walkie-Talkie module along with additional components like an OLED screen, speaker, microphone, and a slot for a 18650 battery. An ESP32 gadget with a stylus-equipped LCD display was also on show. The T-TWR is said...

Chinese designer and manufacturer of IoT hardware MOKO Smart has developed a smart plug for energy management applications in smart home ecosystems. The company chose to integrate Nordic Semiconductors’ nRF52833 system-on-chip as the device’s main processor for running sensor-based...

What is a Signal? One of the definitions of 'signal' in the Merriam-Webster dictionary is: "A detectable physical quantity or impulse (as a voltage, current, or magnetic field strength) by which messages or information can be transmitted from a source to a destination." A signal is...
