Technical datasheet for the Shanghai Weique AW-CO-1000 CO sensor unit, detailing specifications, electrical parameters, and UART protocol.
The document describes the Shanghai Weique AW-CO-1000, a solid-state electrochemical sensor module designed to convert CO gas signals into digital data via UART transmission. Developed by Shanghai Weique Sensing Technology Co., Ltd., this unit is pre-calibrated at the factory and features high sensitivity, low noise, small dimensions, and stability suitable for industrial safety and air quality monitoring applications.
Key technical specifications include a standard measurement range of 1000ppm with a minimum detection limit of 10ppm. The device operates on a voltage supply between 4.5V and 5.5V with a maximum current draw of 5mA. It communicates via a 5-pin interface using UART protocol at 9600 baud, 8 data bits, no parity, and 1 stop bit. This manual is written in Chinese.
