Help with project using a PIR to activate a HC-SR04 sensor

[burton666]

I wonder if it is possible to add two PIRs and two HC-SR04 ultrasonic sensors so that if any of the PIRs trigger both HC-SR04 will start measuering?
I know that the HC-SR04 can not measure at the same time but but if newPing library is used that is fixed automaticly, right?
