Description
The frequency of the Microwave radar motion sensor module is 5.8GHz. This microwave module will not affect any 5 GHz home WIFI devices. The microwave motion sensor can also be used as the alternative of PIR motion sensors. This doppler motion sensor gives a wider angle field of view. In the shape, it is slimmer than the PIR sensor. This radar sensor consumes less power. This sensor uses less power so you can use this Microwave radar module over the PIR sensor. It operates on 5.8 GHz frequency so it will work through walls also. You have to attach a microcontroller with it to process the data. Hold that sensor as the board with the white connector facing away from you, the rightmost pin R1 is Analog output pin. The center pin is just for ground and the left most pin is for Vcc. You can give 5V with Arduino.
Specifications :
- Working voltages are between 3.3-20VDC
- Standby quiescent current is <3mA
- Transmit power is <2mW
- The working environment temperature is almost -20 ~ +80 Centigrade
- it has Repeat Trigger by default
- The output signal is a TTL level. it will high->3.3V/ and it will Low->0V
- Detection angle is 360°(spherical) no dead ends
- Detection range is almost 3-8 meters/16-26ft, the default setting about 7 meters
- The working delay is 1 second to hundreds of seconds, the default setting 30S.
