the detector does not work from the battery. when connected to 5V it works great. when the 5V power supply is lost and restored back is the alarm triggered ?! you do not order this sensor from this dealer. I sent him a video where it was clear to see that the sensor was not working. stretched time until consumer protection ended. I do not recommend
