C2H4 gas sensor Module Outline

C2H4 Gas sensor module Ethylene monitor for Fruit Ripen

This module uses 0.4-2.0V analog signal for transmission, which reduces the interference in the transmission process. It uses imported electrochemical sensors and industrial-grade high-stability single-chip microcomputers. Its products have long life, low cost, high precision and good long-term stability. Features. At the same time, it has a digital output. The serial port communication baud rate defaults to 9600, the data bit is 8 bits, 1 stop bit, and no parity; its output is RS485 (standard Modbus-RTU).
