Ⅰ product introduction
1.1 Product Overview
The wireless flammable gas sensor is a sensor that uses a wireless network for transmission. It does not require a special communication line. It can rely on the ubiquitous mobile phone signal network. The product is excellent in waterproofing and can adapt to long-term field environment work.
This device supports multiple wireless working modes, including traditional GPRS mode and 4G mode, as well as low-power modes such as new Lora mode and NB-IOT mode. Supports city power DC power supply, and also supports battery power for Lora and NB connection.
This equipment measures flammable gas data in real time and transmits it using a wireless network. The network transmission of this product adopts a stable and reliable carrier network, mature technology and stable transmission, strong signal and wide coverage. At the same time, the device supports timing data collection and active upload to the server platform.
