Overview

The MS-1101-01A is a multi-parameter sensor module designed for environmental monitoring using the industry-standard RS-485 Modbus RTU protocol. It integrates carbon dioxide (CO2), temperature, humidity, and ambient light (ALS) sensing into a single flush-mount enclosure. Operating on a wide 9V to 24V DC supply, it is engineered for seamless integration into building automation and industrial control networks.

Why Choose This Part

This module simplifies wiring by providing four distinct environmental sensors over a single RS-485 Modbus interface. Its wide input voltage range (9V-24V) and low power consumption of approximately 112mW make it ideal for long-distance industrial cable runs. The device features a wide ambient light measurement range from 0.001 to 100K Lux, suitable for diverse lighting environments.

Applications

HVAC Control Systems
Monitoring CO2 levels and temperature to optimize ventilation and energy efficiency in commercial buildings.
Industrial Greenhouse Monitoring
Tracking humidity, ambient light, and gas concentrations to maintain ideal growing conditions for crops.
Smart Building Automation
Providing ambient light data for automated lighting control and humidity/temperature data for occupant comfort.
Indoor Air Quality (IAQ) Reporting
Standardized monitoring of air quality parameters for regulatory compliance and health safety in workspaces.

Getting Started

To interface with the MS-1101-01A, connect the RS-485 A and B lines to a Modbus master and provide a 9V-24V DC power source. Use a standard Modbus RTU polling tool to read the input registers for CO2, temperature, humidity, and light intensity. For physical installation, consider using the MA-0101-01A JST cable and the LA-1701-01A swivel mount for optimal sensor positioning.
