DAQ-GP-TLL4G Wireless Liquid Level Sensor Terminal is a wireless liquid level measurement product launched by Shanghai DAQ-IoT Network Technology Co., Ltd. The principle is to use a Wheatstone bridge on a diffusion silicon wafer, and apply pressure to the measured medium (gas or liquid) to change the resistance value of the bridge wall (piezoresistive effect), generating a differential voltage signal. This signal is then converted into a standard analog signal or digital signal corresponding to the range by a dedicated amplifier, and can be further converted into the pressure corresponding to the liquid level of the measured liquid. Due to the proportional relationship between different liquid level depths and liquid pressure, this proportional relationship can be used to determine the water level of the liquid being measured. This product has strong anti-interference, overload and impact resistance, low temperature drift, high stability, and high measurement accuracy, making it an ideal liquid level measuring instrument in the field of industrial automation.
Sensor The terminal supports communication methods such as 4G/WiFi/LoRa by default, and supportsMQTT、 HTTP and other communication methods, SZY206/SZY427/SL651 protocol can overcome wireless communication obstruction caused by special on-site environments, greatly simplifying on-site deployment time and reducing construction costs.

5 Data reporting communication Protocol
5.1 Protocol Explanation
Multiple push methods such as UDP/TCP/MQTT/HTTP require users to provide the public IP (or domain name) address and port number of the cloud server when receiving data.
Example of JSON format data message:
{"depth":122,"ID":"860344048491162"}
Message parsing:
{
Depth ": 122//Liquid level depth value, unit: cm
ID ":" 860344048491162 "//Device ID
}
5.2 Protocol Customization
If you need to customize other communication Protocol, you can contact the business personnel for communication.
6 platform integration
6.1 Default platform
The product is connected to our designated industrial IoT platform by default when it leaves the factory. The platform interface is as follows:

Example of PC browser interface

Example of WeChat Access Interface on Mobile
6.2 User specified platform
Taking Alibaba Cloud platform integration as an example, after users create products and add devices on Alibaba Cloud IoT platform, they need to provide a triplet: {ProductKey, DeviceName, DeviceSecret} and the MQTT topic to be published.
For example, the values of a triplet are:
ProductKey = b0FMK1Ga5cp
DeviceName = 862991419835241
DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q
7 Precautions
This product comes with a default built-in IoT SIM card at the factory, with an annual data fee of approximately 20 yuan, including free technical support and maintenance fees. If you need to use your own SIM card, please inform us in advance.
