ZCT330Mx-xWP-xN-YKx NB-IoT Tiltmeter Datasheet

ZCT330Mx-xWP-xN-YKx NB-IoT Tiltmeter Datasheet Designed by Shanghai Zhichuan Electronic Tech Co., Ltd., high-accuracy technology communication. The maximum measuring range is ±30 degrees, with alarm function. The default protocol is CTIOT (based on China Telecom platform), while MQTT (connectable to Onenet platform) and CoAP are optional. municipal administration, telecom, public utility and many other areas. Safety control Made using industrial class components Stable and reliable performance Ultra-low power consumption IV. Specifications (Unless otherwise noted, the following parameters...

Peak Current Battery included Note 1: Lithium Thionyl Chloride batteries should never be recharged, otherwise they may explode. When a battery is out of power, please replace it in time, do not charge it! Note 2: The self-discharge rate of the battery is less than 3% a year, if it is stocked at room temperature (25°C). The self-discharge rate becomes higher if the battery is stocked at a higher temperature.

uploads data to the server. Note 3: Alarm accuracy refers to the angular error when the product triggers an alarm. Suppose the alarm angle is 3 degree and the alarm accuracy is 0.03 degree, if X and Y axis angle are smaller than 2.97 degree, alarm will not be triggered, if X or Y axis angle is between 2.97 and 3.03 degree, alarm may or may not be triggered, if X or Y axis angle is larger than 3.03 degree, the alarm will be triggered for sure. Note 4: Alarm delay time refers to the time when the product continues to tilt beyond the alarm angle to trigger an alarm. Note 5: Estimation is based...

When the tiltmeter tilts beyond the alarm angle, alarm will be triggered and the tiltmeter will upload the alarm frame every 60 minutes. The first detected alarm angle value will be used as the angle value in the alarm frame. The tiltmeter detects itself every 60 seconds until its tilt angle is smaller than the alarm angle again, then the alarm function is automatically restored. If the alarm frame is not successfully uploaded, the tiltmeter will upload it at intervals of 5 minutes, 15 minutes, 30 minutes and 60 minutes until the alarm frame is sent successfully. After the alarm frame is...

Note 1: When carrying a sequence number, the data packet must contain 1 byte of data ID, 1 byte of data length, and 4 bytes of data content. Please refer to Appendix. Note 2: When the device is reset to default factory settings, the heartbeat interval, alarm angle, alarm delay time, relative angle and enable/disable...

When backup server is not set, if the device fails to upload data to the server, it will lose the data and enter standby mode. When backup server is enabled, if the device fails to upload data to the server, it will re-send the same data to the backup server; if it fails to upload data to the backup server, it will lose the data and enter standby mode. 9. CoAP protocol 9.1 In case of obtaining real-time data of the device via telemetry messages, the default URI is /api/v1/ZCIMEI/telemetry, where IMEI refers to IMEI of the device. For example, IMEI is 864823042076612,...

For example, if IMEI is 864823042076612, the client attributes URI of...

9.3 Share attributes The default URI of share attributes is /api/v1/ZCIMEI/attributes, where IMEI refers to IMEI of the device. For example, if IMEI is 864823042076612, the share attributes URI of the device is /api/v1/ZC864823042076612/attributes. The device requests the server to send data through GET. The data type of share attributes messages is json. Please follow below format: { "alarmEnable":true, "alarmAngle":3, "alarmDelayTime":20, "relativexAngle":0, "relativeyAngle":0, "heartbeatTime":3600 } Key alarmEnable Value true or false Default true Value Type Boolean type Description True...
