NB Intelligent manhole cover sensor

Manhole cover detectors for urban roads, built-in gyroscopes to detect manhole cover rollover and other faults, and through the NB network reporting platform, the deployment of the "urban manhole cover" intelligent real-time monitoring IoT system can be quickly implemented without wiring, greatly reducing the construction time of the real-time monitoring system And reduce the implementation cost of the system. Realize the functions of monitoring the state of the manhole cover (opening, displacement, and tilt), real-time alarm, automatic inspection, and timely disposal to ensure safe operation, further improve the level of informationization and intelligence of municipal management, and lay the industry application foundation for smart cities.                   

Combined electrical fire monitoring detector

Scheme composition: CT-X100 + XE3112SWL + XE5130
Introduction: This scheme supports the acquisition of 1/2/4/8 channel temperature, residual current, line current, and three-phase AC voltage data detection. A variety of communication methods (default is NB-IOT communication mode), transmitted to the Internet of Things platform.

ZK-WM-NBC203 camera water meter

Power supply: 3.6V battery

Static power consumption:<0.15 mW

NB smart water meter

Electronic pulse-type water readings are obtained and managed by the NB reporting platform.

For new installation areas. Remote meter reading of water meters, collection and statistical analysis of real-time cumulative usage, calculation of user water consumption and calculation of water charges, each water usage can be checked and traced.

Remotely switch on and off the meter to prevent malicious arrears.

Provide user binding function, bind user contact method and payment method to water meter, which is convenient for management personnel to manage payment.

Provide alarms for abnormal operation of water meters, and provide alarms for illegal opening of water meters and reversed water meters to ensure water safety.
