What is the transmission method of gas detectors? Take the HNAG1000-O2-F series as an example.

The HNAG1000 series typically offers two transmission methods: wired and wireless.

In wired transmission, there are four types of signals, namely:

4-20MA: Known as the three-wire system, analog output.

2. RS485: Known as a four-wire system, digital quantity output.

3. Switching quantity: 110V passive output.

What are the types of remote transmission?

Generally, there are three types: 4G, LoRa, and Wi-Fi.

1. 4G: As the name implies, 4G refers to a data upload cloud platform, which provides a website URL to users.

2. LORA: It features a transmitter and a receiver, with the receiver installed on the host computer or PC.

3. WiFi coverage is essential.

Without interference, LoRa can cover distances of 10-50 kilometers. As for USB transmission, it's generally achievable as well, either through RS485 to 232 or USB conversion. Got it, everyone?!
