Description:
GH100 Miniature Microwave Motion Sensor is a X-Band Bi-Static Doppler transceiver module. Its built-in Dielectric Resonator Oscillator (DRO) and a pair of Microstrip patch antenna array, make it ideal for OEM usage in motion detection equipment. This module is ideally suitable for false alarms reduction in intruder detectors when work together with Passive Infrared (PIR) sensor. It can also be used for auto-door opening and vehicle speed measurement.Features:
- Low current consumption
- CW or Pulse operation
- Flat profile
- Microwave-PIR motion detector
- Speed measurement
- Lighting control
- Long detection range

This is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE it is a great way to jump into electronics, or perfect for when an Arduino is too big or too much. Features : -Support for the Arduino IDE 1.0 (OSX/Win/Linux). -Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection). -On-board 500ma 5V Regulator. -Built-in USB. -6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB). -8k Flash Memory (about 6k after bootloader). -I2C and SPI (vis USI). -PWM on 3 pins (more possible with Software PWM). -ADC on 4 pins. -Power LED and Test/Status LED.
