AN-101C is an improved wireless geomagnetic product independently developed by Weichuan Technology, which detects the occupancy/vacancy status of parking spaces by burying them on the ground surface. When a vehicle parks or leaves a parking space, the geomagnetic field detects the presence of the vehicle based on changes in the surrounding magnetic field, and transmits the parking space status information as a digital signal through the LoRa gateway to the cloud monitoring platform. The cloud monitoring platform processes and analyzes the data, and interacts with the application platform to achieve real-time monitoring of the parking space status in the parking lot. AN-101C has the characteristics of long transmission distance, low power consumption, stable performance, high vehicle detection accuracy, no wiring required, simple installation, long maintenance interval, and low cost. This product supports Bluetooth wireless configuration and wireless calibration, improving maintenance efficiency; Built in ultra large capacity industrial grade battery, using automatic algorithm, with a battery life of over 5 years. Widely applicable to urban road parking, scenic spot parking, community parking and other scenarios.
