Parking occupation detector is sensor that combining ultrasonic and magnetic technology. Moreover, with the redundant technology of the sensor, it achieves an accuracy of 99%. The error has only happened while extreme environments, like floods and thunder at the same time. From the performance, it overwhelms the lonely magnetic products.
Here are the features of Lorawan Parking Sensor
1. Embedded installation method: Make one hole on the ground which can put the sensor into. No need to be much bigger, it is enough if the top cover of the sensor can be at the same level as the ground.
2. Install the sensor on the ground.
