Product Overview

The SGX Sensortech PS1&PS4-CO-1000-MOD series carbon monoxide modules are advanced sensing solutions combining a revolutionary 'Solid Polymer Electrolyte' technology with an intelligent printed circuit board. These modules offer high accuracy, fast response times, and low power consumption, making them ideal for IoT applications and demanding industrial environments. Featuring a stable zero point, good anti-toxicity, and a lifespan of over 5 years, they provide reliable carbon monoxide detection. With a standard UART digital output and plug-and-play functionality, they are easy to integrate and operate without requiring specialized sensor knowledge. Applications include early warning systems for domestic fires, automobile lithium battery failures, security monitoring, industrial fuel burning, and more.

Communication Protocol

The module uses serial communication with the following parameters:

• Data bits: 8 bits
• Baud rate: 9600
• Stop bit: 1 bit
• Parity bit: None

Communication modes include Active Upload and Q&A. The default mode after power-on is Q&A. Commands are available to switch between modes. After power-off or switching to low power mode, the mode reverts to default.

Key Commands:

• Command 1: Switch to active upload.
• Command 2: Switch to passive upload.
• Command 3: Get sensor type, maximum range, unit, and unit decimal places.
• Command 5: Actively read gas concentration value.
• Command 6: Read gas concentration value and temperature/humidity combined.
• Command 7: Get current temperature and humidity.
• Command 8: Get current temperature and humidity with calibration.
• Command 9: Get current version number.
• Sleep Mode Commands: Enter sleep mode, Exit sleep mode.
• Running Light Commands: Turn on/off running lights, Query running light status.

Communication Protocol Details:

• Checksum: Calculated by adding data from bits 1-7, inverting each bit, and adding 1.
• Decimal Places: Bits [4]~[7] determine the number of decimal places.
• Data Sign: Bits [0]~[3] indicate positive (0) or negative (1) inhibition.
• Units: 0x02 (ppm and mg/m3), 0x04 (ppb and ug/m3).
• Temperature Calculation: T = (float)((int)((0x0A<<8)|0x09))/100 (°C)
• Humidity Calculation: Rh = (float)((uint)((0x0A<<8)|0x09))/100 (%RH)
