1. Functional Features

Wireless communication with GRS-DC-I or GRS-DC-O temperature and humidity measurement points, with a wireless communication distance of up to 1000 meters and the ability to penetrate 3-4 floors indoors.

Automatically identify whether the wireless measurement point is communicating normally, the remaining battery level of the wireless measurement point, etc., and report them.

Supports uploading data through any method such as RJ45 network port, GPRS, RS-485, etc.

Support SMS alarm in offline mode (such as computer power failure or shutdown, etc.), and the alarm content can be customized.

Large screen Chinese LCD display with a simple and friendly interface.

Built in data storage, capable of storing 140000 records, and can be exported through 485 connection to the software platform.

■ Support online printing of records (optional printer required)

Equipped with 1 channel of 0~220V AC voltage input detection, it can be used for power outage alarm in the city.

■ DC 9-35V wide voltage supply.

The device has a unique 32-bit address, which is easy to manage and identify, and can be paired with various software platforms of our company.

Access monitoring platform

The GRS-XZJ-100 small host can be connected to the following platforms

Platform 1: GRS-RJ-WEB software platform. This platform is deployed on customers' computers or servers, and devices upload data to the platform through GPRS or Ethernet cables. For a detailed introduction to the GRS-RJ-WEB software platform, please refer to the "GRS-RJ-WEB Software User Manual".

Platform 2: GRS-RJ-Q software platform. This platform is deployed on client computers or servers, and wireless hosts can upload data to the GRS-RJ-Q software platform through GPRS or Ethernet ports. If there is no network port on site or the customer does not want to use GPRS, a two core cable (RS485 bus) can be used to connect to a computer or server and send the data to the monitoring platform. This application mode supports devices to send the data stored on the device to the monitoring platform.
Platform 3: Cloud monitoring platform. If the GRS-XZJ-100-W small host sends data to the cloud monitoring platform, the device setup is the simplest, and customers do not need to build their own servers. Simply plug the small host into an internet cable or phone card, and there is no need to configure any additional parameters.
