Inclination alarm manhole cover sensor

GTi-S2021 or intelligent well cover with three proofing

transmits data through GPRS or NB-IoT or LoRaWAN as you need.

When the manhole cover is opened abnormally, contact

automatically bounces and triggers alarm device, sending alarm

information to platform to realize remote supervision. In this

manner infrastructure will be well protected and make municipal

management smarter, laying a solid foundation for building a smart city.

1.Low Power Consumption: The device is designed with chips consuming ultra-low power in its master

control and an intelligent sleep mode. And its built-in battery can be used for more than 3 years

in practical application.

2.Low Cost: As the device uses the network type of NB-IOT or LoRaWAN, wireless network transmission

is farther and more stable. In so doing, both labor and equipment cost will be saved a lot.

3.Flexible Deployment: Travel switch is used to help monitor the state of the cover. If it detects

any movement or opening of the cover, alarm mechanism will be triggered in the first time. It makes

the alarm activate on time and more accurately.

4.Security & Reliability: It is well verified through a number of application tests that the device

is highly secure and reliable. That is attributed to its unique wireless network transmission,

ultra-low power consumption and reliable alarm triggering.

5.Water Resistance: The device can continue to work when it is immersed in 1 meter-deep water.

6.Extension: The internal control component of the device reserves extended function interfaces.

The device can be connected through RS485 interface sensor, A/D analog interface sensor and I/O

digital interface sensor.
