Chapter 1 Product Introduction
1.1 Product overview
Our self-developed LoRaWAN carbon dioxide three-in-one device has the characteristics of small size and integration. It is convenient to transport, carry and install, and can be adjusted dynamically at any time. The appearance of the equipment,working conditions, safety requirements, functional requirements and communication requirements can all be adapted to different measurement environments.
The device measures data in real time and uses wireless networks for transmission. The product network transmission adopts a stable and reliable operator network with mature technology, stable transmission, strong signal and wide coverage. At the same time, the device supports timing data collection and active upload to the server platform.
1.2 LoRaWAN features
1.Transmission distance: up to 1km in towns, up to 3km in open suburbs;
2.Working frequency: ISM frequency band including 433, 868, 915 MHZ, etc.
3.Modulation method: based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with forward error correction (FEC) capability, proprietary patented technology of semtech;
4.Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer
4.Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer
the transmission distance.
1.3 LoRaWAN product advantages

2.2 Product appearance
The following is the appearance size of the product, you can install the sensor reasonably according to the product size, as shown in the figure:
(1) Battery powered version
(2) Power supply version
(2) Power supply version
2.3 How to use
(1) In the first step, the LoRaWAN gateway uses a power adapter for power supply.
(2) In the second step, if the LoRaWAN node is powered by a battery, press the sensor power button; if the LoRaWAN node is powered by a power adapter, just send the power adapter delivered by our company to supply power.
(3) After the LoRaWAN gateway and the node are powered on, the node and the gateway establish a connection through the wireless network, and the sensor will report the collected data to the gateway according to a certain frequency.
(4) There are two ways to view data, one is in the LoRaWAN gateway; the other is that users can view data on their own private server or TTN server.
2.4 matters needing attention
(1) For the use of LoRaWAN gateway, please refer to the gateway manual.
(2) Use outdoors, and cannot be placed in a low-lying, confined environment.
(3) LoRaWAN gateway needs to be placed in a higher position to enhance signal reception.
(4) Moisture-proof and high-temperature treatment should be done for outdoor use.
