POE or Power Over Ethernet is a technology that lets electrical power to be transmitted along with data over standard Ethernet cables. This eliminates the need for separate power cables and power supplies for networked devices, making it a convenient and cost-effective solution for powering and connecting devices in networked ...

This is the FE1.1s chip a USB 2.0 hub controller chip developed by a company called Fortune Semiconductor Corporation. This chip is designed to provide additional USB ports to devices, allowing users to connect multiple USB devices to a single USB port on their computer or other devices. This chip ...

This is another example of how to wire the TMP461. The TMP461 is a high-accuracy remote and local temperature sensor developed by Texas Instruments, this device has a pin-programmable bus address and also operates on the i2C protocol driven by a low-power with a high accuracy temperature sensing. Another feature ...

This guide we will going extend / amplify the 433 MHz radio signal with MAX263AXT. However, HC-12 alone already reach to 2KM (2000 meter in open range ) so perhaps we can extend it more with the help of MAX263AXT LNA. The MAX2634 LNA (Low-Noise Amplifier) combined with low-power shutdown mode enhanced ...

In ESP32 there is a feature that you can encrypt data or messages using ESP-NOW technology developed by Espressif System. With this feature, we now transmit encrypted data from one ESP32 to another This communication protocol is running in low-power, secure and direct wireless to wireless communication that enables multiple ...

How i3C Works and Its Applications The use of sensors in mobile devices has grown it is becoming complex for manufacturers to utilize existing methods like i2C & SPI. So, the MIPI alliance members launched the first i3C protocol which is also called (Improved Inter-Integrated Circuits) in the year 2017 ...

Another illustration that demonstrate how to wire the ESP32-WROOM set as client talk to ThingSpeak API. As you can see the diagram below, we will be going to build a non-contact temperature sensor using MLX90614. Unlike DHTXX, LMXX, HDCXX, HTUXX, compare to MLX90614 it has an integrated IR to calculate ...

HTU21D is a digital humidity sensor with temperature output that uses MEAS (Measurement Specialties), the chip has embedded in a reflow solderable Dual flat leads (DFN) package with a size of 3X3X0.9MM. The HTU21D provides a calibrated linearized signal in digital, additionally, it communicates using TWI / i2C protocol. These ...

ESP8266 is capable to transmit and receive data via WiFi. ESP8266 can be configured or set as a basic server and access point. On this guide, we will be going to configure the ESP8266 to talk to each other without the help of the network router. As you can see ...

NTP (Network Time Protocol) is a networking protocol for clock synchronization between computer over packet switches, variable-latency data networks. NTP is one of the oldest IP in current used, this technology was designed by David Mills at the University of Delaware. NTP is intended to synchronize all participating computers within ...
