Hi ,
I am wondering if human presence sensor is good for my product. I am looking for a sensor that can detect if people sleep in the room even if they don’t move. Also the detector should transmit the status to the reciever that will activate the circuit breaker and the electricity in the room.
Hello @Elik1111 and welcome to the RobotShop forum,
I am wondering if human presence sensor is good for my product. I am looking for a sensor that can detect if people sleep in the room even if they don’t move.
The way the sensor works is: it first emits FMCW and CW radio waves to the sensing area. Next, the radio waves, reflected by all targets which are in moving, micro-moving, or extremely weak moving state in the area, are converted into electrical signals by the millimeter-wave MMIC circuit in the sensor system. After that, these signals will be sent to the processor and processed through the related signal and data algorithms. Then, the target information can be solved out.
However, you should check if the detection distance (9m) and beam angle will work for your product (100×40°).
You could also check these other options:
Also the detector should transmit the status to the reciever that will activate the circuit breaker and the electricity in the room.
To do this you will also need a microcontroller, the sensors/boards I linked are all compatible with Arduino. And you will also need a relay.
