Overview
The SF6 sensor in the infrared SF6+oxygen+temperature and humidity module uses the principle of infrared spectral absorption (NDIR) to detect the SF6 content in the air. The oxygen sensor uses an electrochemical sensor, and the temperature and humidity sensor uses a temperature and humidity integrated digital sensor. This module adopts imported high-precision sensors and industrial grade high stability microcontrollers, which have the characteristics of long service life, low cost, high accuracy, and good long-term stability. The baud rate of serial communication is missing $r $n and is 9600, with 8 data bits, 1 stop bit, and even parity; Its output interface is: four channels of 4-20mA current output, and one channel of RS485 $r $n output signal.
