## Description

Full description not available

## Features

- The microwave motion sensor is a microwave moving object detector designed by the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting the microwaves reflected by the object. The detection object will not be limited to the human body, but there are many other things.
- Non-contact detection; Adapts to harsh environments without affecting by temperature, humidity, noise, airflow, dust, light, etc. Powerful anti-RF interference capability; Low output power, no harm to human body; Long detection distance.
- Can detects of non-living objects; The microwave moves at the speed of light with great directionality. Compatible with Raspberry Pi and Arduino Board.
- Used in industrial, transportation and civil applications such as measuring, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc.
- Note: There are ultra-high frequency MOS devices inside the microwave motion sensor. If you try to use battery power to test during the test, this can avoid the breakdown caused by the static pressure difference between the power supply and the test device, such as the oscilloscope; in addition, when the product is in use, Please try to choose battery power supply to ensure the best detection effect.

## Questions & Answers

**Q: I reversed the power input. caught the mistake within 5 seconds, disconnected. now the amber detection light stays on always. did i fry it?**
A: Hello! You can try to adjust the potentiometer on the back of the sensor (turn it clockwise to decrease the sensitivity), it may be that the sensitivity is too high, causing the detection light to stay on.

**Q: can this be used with a 24vt power supply to power a light bar? needing repeat motion detection in a warm enviroment 100-118 degrees**
A: No, max voltage is 5V. Also the output would not drive a LED light bar. You would have to use a relay.

**Q: Is there any way to disable the visible light on it?**
A: hi, friend
This product cannot disable visible light. Sorry, it did not help you! Sincere regards!

**Q: Battery power is better then  mains power??  Am i understanding the product info correctly?**
A: Hello! The working voltage of this product is: 3.3V/5V, which is generally connected to the power supply interface of the single-chip main board, and the single-chip main board is responsible for the power supply. Generally, the output voltage of the single-chip main board is 3.3V/5V. The following is the wiki URL of this product for reference:
