Review: Easy to mount - The device has two large, easy to use, mounting holes.
Review: Good in theory, useless in practice because of inadequate documentation - Review has been downgraded to 1 star after email discussions with CQROBOT support. This looks in theory like an affordable and very capable sensor but has one massive problem. The documentation on the CQROBOT Wiki doesn't explain key functions of the sensor adequately to program it. E.g. there is a command to set the motion sensing delta value, but nowhere does it say what the 16 bit delta value actually does. The same is true for other parameters like the motion sensing distance level which takes a value of 0 to 15, but nowhere does the documentation explain what the values mean. Also there is a command to "set lighting time" with no explanation of what the lighting time actually does. I haven't been able to find a data sheet online anywhere for the AT5820 chip that explains these values in detail. I contacted CQROBOT support who said:" For the time being, we can only provide customers with basic test code and basic technical parameters of the product". So basically this product is useless because key commands are inadequately documented and the supplier has no intention to document them. Don't waste your money until / unless CQROBOT provide adequate documentation.

## 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.
- It is used in industry, transportation, industry, agriculture, smart home, security monitoring and other fields.
- 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.

### ⭐⭐⭐⭐⭐ Review
*by A***Y on 11 January 2023*

Wie schon von CQRobot gewohnt, erhielt ich das kleine Modul in einer Plastikbox verpackt, bereits bastelfertig mit Kabeln und Dupont-Buchsen versehen. Die Platine ist gut gefertigt und bestückt mit einem kleinen Spannungswandler, ein paar Widerständen, Kondensatoren, einem Quarz und einem kleinen Chip, der einen Mikroprozessor mit eingebautem Mikrowellen-Bewegungssensor beherbergt. Weiterführende Infos erhält man ebenfalls wie gewohnt auf der Wiki-Seite von CQRobot. Sehr gut an dem Modul gefällt mir, dass es auch völlig autark funktioniert, da der eingesetzte Mikrocontroller einen Flash-Speicher besitzt, in welchem die Einstellungen bspw. zur Empfindlichkeit oder der Einschaltzeit des Bewegungssensors nichtflüchtig gespeichert werden. Je nach Schaltzustand lassen sich am Ausgang des Moduls dann High oder Low Level abgreifen und weiter verarbeiten zur Ansteuerung weiterer Elektronik. So ließ sich für den ersten Test das Modul auch ganz ohne Einplatinencomputer in Betrieb nehmen. Ich stellte dann fest, dass die Unterseite der Platine in die gewünschte Erfassungsrichtung zeigen muss. Das geht aus der Beschreibung von QCRobot nicht eindeutig hervor. Dann reagiert das Modul sehr sensibel und zuverlässig auf alle Bewegungen im Erfassungsbereich. In der Grundeinstellung des Moduls fällt der Ausgang sofort wieder auf Low-Pegel, sobald es keine Bewegung mehr erkennt. Ich hatte ein Multimeter zur ersten Messung des Schaltausgangs angeklemmt und anschließen eine kleine, schon vorbeschaltete Relaisplatine, die dann eine LED-Lampe ansteuerte, was auch prima funktionierte. Wie viel der Ausgang leistet, geht aus der Beschreibung nicht hervor, aber es werden sicher nur wenige mA sein, so dass sich dieser nur zum Ansteuern sehr kleiner Lasten eignet. Zum weiteren Test verband ich dann das Modul mit einem Arduino, spielte den kleinen Sketch auf, den ich auf der Wiki-Seite fand und konnte dann im seriellen Monitor der Arduino-IDE die Schaltzustände auslesen. Auch das funktionierte problemlos. Um das Modul allerdings nach seinen Wünschen programmieren zu können, ist dann doch etwas mehr an Programmiererfahrung nötig. Das Modul kommuniziert über die UART-Schnittstellen mit einem angeschlossenem Einplatinencomputer. Das Kommunikationsprotokoll wird auf der Wiki-Seite beschrieben und erlaubt das Programmieren und Auslesen der Register der MCU auf dem Modul. Da muss auch ich mich erst etwas einarbeiten, sollte aber problemlos gelingen. Für eigene Experiment oder auch den Aufbau einer eigenen Steuerung scheint das Modul wirklich gut geeignet.
