HB100 Microwave Doppler Radar Wireless Motion Sensor Module
HB100 Microwave Doppler Radar Wireless Motion Sensor Module
The HB100 Miniature Microwave Motion Sensor is a module that uses X-Band Bi-Static Doppler technology to detect motion. It consists of a Dielectric Resonator Oscillator (DRO) and a pair of Microstrip patch antennas, which make it suitable for motion detection equipment.
This module can be used for various applications, such as alarms, motion detectors, lighting control, vehicle speed measurement, and automatic doors.
Doppler Principle
The text below explains the Doppler effect based on time. When radio waves encounter a moving object, they will be reflected by the object. The frequency of the reflected waves will change depending on the motion of the object. If the radio waves encounter a stationary object, then the frequency of the reflected waves will be equal to the frequency of the transmitted waves. If the object moves towards the source, then the reflected waves will be compressed, which will increase their frequency. On the other hand, if the object moves away from the source, then the reflected waves will be stretched, which will decrease their frequency.

HC-05 Bluetooth Wireless UART Module
HC-05 is a Bluetooth Transceiver Module and has TTL Output. HC-05 6 Pin Wireless Serial Bluetooth Module is a Bluetooth module for use with any microcontroller. It uses the UART protocol to make it easy to send and receive data wirelessly. This Bluetooth module is a completely qualified Bluetooth V2+Enhanced Data Rate (EDR). It is 3Mbps Module with 2.4GHz radio transceiver and baseband. It has CSR Bluecore 04, an external single-chip Bluetooth system with CMOS technology and AFH, Adaptive Frequency Hopping, feature.
The HC-06 module is a slave only device. This means that it can connect to most phones and computers with Bluetooth but it cannot connect to another slave-only device such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave.
Specification and Features:
- Voltage supply: 3.5v to 5v
- Working current: matching for 30 mA, matching the communication for 8 mA.

HDMI-Compatible Virtual Display Emulator 4K HD DDC EDID Dummy Plug Dongle

Basic Electronic ComponentsHDMI-Compatible Virtual Display Emulator 4K HD DDC EDID Dummy Plug Dongle
This HDMI-Compatible Virtual Display Emulator 4K HD DDC EDID Dummy Plug is a small low-cost DVI EDID Dummy Plug that emulates a high-resolution display to make the computer run “headless” (without a keyboard, mouse, and monitor).
By simulating the presence of an attached display, the emulator allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be disabled when there is no screen available.Once the HDMI Dummy Plug is attached to the video output socket in your computer, your operating system will detect a connected display that enables the GPU external adapter.
It appears as a headless ghost display in the OS graphics card adapter plug properties window for easy identification. GPU hardware is often disabled until a display is attached resulting in poor performance and a limited working resolution for remote users.
With the GPU enabled, it is possible to play games and stream as well as enjoy native high-resolution remote desktop access for workstations, and provide stability to cryptocurrency mining rigs.Works with PCs, and any other device with HDMI output. HDMI 2.0, rx460, GTX1050, or above is required for 4K.
