| Code produit: | HC-SR505 |
The HC-SR505 is the little brother of the HC-SR501 which means it sure lacks some of the HC-SR501 functionality such as:
1- Single/Repeated triggering is not adjustable. The HC-SR505 triggering is repeatedly by default
2- The HC-SR501 range is around 7 meters while the HC-SR505 is around 3 - 4 meters
3- The delay between repeated triggering is not adjustable
Still, the HC-SR505 enjoy some features where it outbeats the older brother such as:
1- Size
2- Very low current consumption which is around 60 uAmps
3- As reliable as the older brother
