Review on π Taidacent Waterproof Ultrasonic Sensor: Accurate Vehicle Presence Detection and Occupancy Monitoring for Outdoor Parking Areas (PWM) by Adam Townsend
Security and surveillance does not last long
Bought three. They have all been fine-tuned using the Arduino Uno and the new Ping library. For a while they work perfectly, nice and stable, and then they fail. The first lasted 4 months. The second and third lasted less than 24 hours. Not waterproof. The rubber grommets around the transducers do not seal well. So basically worth nothing.
- Built-in intelligent algorithm, stable circuit and stable and reliable data output.
- Very expensive
