KS53 LoRaWAN temperature sensor Technical Manual V1.0
1. Product introduction
1.1. Product Introduction
this product is based on the LoRa ® Wireless technology digital temperature sensor, using high-precision sensing elements to collect real-time ambient temperature data, and through the LoRaWAN ® The protocol periodically reports measurements to the application platform. Users can flexibly configure the sampling and reporting cycle through the management platform, and the default setting is to upload data every 15 minutes.
Relying on LoRaWAN ® Standard communication protocol. This product has The advantages of long-distance transmission and low-power operation. It supports access to gateways compatible with various platforms, and is compatible with mainstream IoT platforms such as ThinkLink, ChirpStack, and The Things Network(TTN) to realize remote monitoring and intelligent management of environmental parameters.
It has IP65 level advanced protection, tolerates complex outdoor environment, and is widely used in smart industry, smart buildings, warehousing and logistics, agricultural monitoring and other scenarios to meet the application requirements of all-weather environmental monitoring.

3. Instructions for use
3.1. Network Topology
This product is a terminal device that conforms to the standard LoRaWAN protocol, and its normal operation depends on the complete LoRaWAN network support. The network needs to include a LoRaWAN gateway and a network server (NS), where the Gateway can be a brand-compatible gateway, and the NS must have Protocol resolution and device management capabilities.
Supports access to mainstream LoRaWAN Network platforms, including ThinkLink, ChirpStack, and The Things Network (TTN), ensuring flexible deployment and system integration. Users can use ThinkLink IoT platform to configure the object model, implement rich functions such as data parsing, business logic processing, and card view display, and quickly build application systems for actual scenarios.
A typical LoRaWAN network topology is as follows:
3.2. Working mode
3.2.1. Periodic Collection and Upload
collect the temperature value every 5 seconds and upload the temperature value according to the set cycle. The Upload cycle can be set by NS delivery.
3.2.2. COV Upload
COV mode is supported. When the temperature or humidity changes exceed the threshold, a packet of data can be uploaded. The Upload protocol format is the same as the periodic Upload format.
The default COV temperature threshold is 1°C.
3.2.3. Communication Test
use a magnet to trigger 1S -2s when sticking a two-dimensional code to trigger a packet of upstream measurement data.
3.2.4. Network access
use a magnet to trigger 6s-8s on the two-dimensional code to trigger a packet of network access data.
3.3. Installation
3.2.1. Wall Mount
· fix back panel to wall (keep back panel Arrow Up)
· Tighten the LoRa antenna to the antenna interface
· hitch the temperature sensor to the back plate (slide down after aligning the groove on the back of the sensor with the protrusion on the back of the back plate)
4. Communication protocol
4.1. Data items and identifiers.
LoRaWAN port number = 11
only one data format is supported. Data is sent periodically according to the set period. When a COV event occurs, one frame of uplink data is triggered.
