Ultrasonic Sensor Adopting ultrasonic principle enables PGS to detect parking lots, featured by RED Color Lighting standing for parking lots non-available and GREEN lighting for lots available, and all parking status information is transmitted to information collectors to deal with. Detect units are integrated into one with LED indicating lights, conveniently applicable. Ultrasonic Sensor Feature 1 Repetitious detection, which eliminates the random disturbance and enables the sensor to work stably. 2 Designed according to actual requirement, easy to fit in various projects. 3 Two detecting methods enable it to provide two working modes. User can prefer either mode to detect space occupancy according to actual situation. When the ground is even, detecting accuracy will be higher. Technical specification Working Voltage DC24V Detecting range set-up 8 degrees Peak Current 300mA Max. Detecting Deviation 0.2m Detecting Unit Ultrasonic Sensor Detect range Smaller than 45degree Communication Interface RS485 Temperature -25 to 70 degree Sensing range 30cm-400cm Appearance Dimension 13cmD× 6cmH
