[AG Echo]  Ultrasonic level sensors measure the distance or presence of target objects by sending a pulsed ultrasound wave at the object and then measuring the time for the sound echo to return. Knowing the speed of sound, the sensor can determine the distance of the object.

[AG Echo]  Ultrasonic level sensor module provides range detection and ranging from 200mm to XXXX mm (where XXXX = 1000, 2000, 3000, 4000, 5000, 6000), in a PVC housing. It is designed for indoor and outdoor use. The sensor provides sonar range information with high resolution. There are multiple sensor options available to the user. The users should clearly specify what options are required in their application. The table I below shows the various types of sensor options that are available. The signal lines TX, RX and TRG/OUT can be configured in various possible combinations as shown in the table I. It should be noted that +12VDC and GND are common in all cases. The user is cautioned to only specify the options that are really necessary, because multiple options increase the sensor cost. User specified options not mentioned in table I can be considered for bulk orders.

The controller is a general‐purpose ultrasonic level controller that provides the end user the ability to control up to three unique devices (pumps, valves and/or alarms) through three relays, namely – Relay1 (DPDT, 2 form C), Relay2 (SPDT, 1 form C) and Relay3 (SPDT, 1 form C). The controller uses three push-buttons, SET, UP and DOWN for configuring the relay operation(s). All of the relays can be used for controlling valves, pumps or alarms.

[AG Echo]  Ultrasonic level sensor which provides accurate range detection, automatic calibration and adaptive noise cancellation in software provide reliable and record measurement. All sensor used 4- stage op-amp based low noise amplifier, second order narrow band pass filter, peak-detector and low-pass filter circuit for detecting even the weakest of the reflected sonar signals. Various output options like pulses width, serial analogue 4 to 20 mA, 0 to 5 Volt etc. are available. Interface circuit options provide RS 232, 4 to 20 mA loop, 0 to 5 V DC, buzzer/relay and seven segment LED display. Accessories like mounting bracket rubber washer/nut faster etc. provide quick design and installation support

How Parking Guidance System works:

Ultrasonic sensor is based on ultrasonic principle where time is measured by emission of sonic signal & return of its echo to determine the presence of vehicle.
Detect, Count and Indicate the vacant places.
Vacancy Indicator & Display Panels are based on L.E.D. technology to minimize power consumption & increase visibility with long maintenance-free life.
Master Controller interface with other Parking devices & Zone Controller manages the information on a car park zone or level & communicates with other Zone Controllers & Master Controller.

Benefits of Parking Guidance System:

It is estimated that 30% of traffic congestion during parking is attributed to vehicle looking for parking space (source Traffic Technology International)
Cost optimization by progressive openings of levels as necessary. Closed levels can save electricity by switching off lighting.
Validation of the premium charged for parking by providing efficient and user friendly parking facility.

Advantages to Parking Area Management:

Increase in Car Park Capacity - Due to reduction of circulation space.
Increase in Lot Utilization - Lots in hidden / obscured areas get used.
Reduces Congestion and Improves Traffic Flow - Drivers know where to go.
Vast improvement in the image & ambience of the Car Parking area.
Faster Turnaround of Cars into the Car Parking area.
Self-Diagnostic Features - Convenient for management.
Customer Satisfaction - More likely to return.
Statistical Information - Trends can be monitored.
Increased Security within the Car Parking area.
Increase in Revenue
Less pollution
Cost Effective Solution

Advantage to Car driver:

Shorter Waiting Time at Car Park Entrance
Guided to Nearest Available Parking Space
No Need to Search, Less Stressful
Saves Fuel and Reduces Tyre Wear
Gains Precious Time, More time to Shop or Dine
Prevent Drivers Fighting over Parking Space
Car Parking – A pleasant experience for the motorist
