Infrared CO2 Sensor YWBL-WH 400-2000ppm Serial PWM Module

Description

Product Overview

The YWBL-WH infrared CO2 sensor is engineered to deliver precise carbon dioxide concentration readings across a wide measuring range of 400 to 2000 ppm. Utilizing a non‑dispersive infrared (NDIR) detection principle, the sensor provides stable and repeatable performance even in demanding laboratory environments. Its compact form factor, measuring just a few centimeters in length and weighing only 6 grams, makes it easy to integrate into a variety of equipment, from incubators to gas analysis stations.

Constructed from high‑quality aluminium alloy, the sensor housing offers excellent resistance to corrosion and mechanical wear, extending the operational lifespan well beyond typical industry standards. The device operates on a low voltage supply of 4.5 to 5.25 VDC, resulting in minimal power draw while still delivering fast response times. Two output options are available: a serial communication interface for digital data acquisition and a PWM (pulse‑width modulation) output for analog‑type control systems. An audible alarm is built in to alert users when CO2 levels exceed predefined thresholds, enhancing safety in sensitive applications.

Key specifications include a measurement accuracy of ±(30 ppm + 3% of reading), a humidity tolerance up to 85 % RH, and a temperature operating range suitable for most laboratory conditions. The sensor is calibrated at the factory and comes with a detailed data sheet that outlines wiring diagrams, command sets for serial communication, and recommended mounting procedures. Its lightweight design and low power requirements also make it an excellent candidate for portable or battery‑operated devices, though the sensor itself does not require an external battery.

Designed with expandability in mind, the YWBL‑WH model can be easily incorporated into larger monitoring networks using standard serial protocols. This flexibility allows users to scale from a single‑sensor setup to multi‑sensor arrays without significant redesign. The sensor’s firmware can be updated via the serial interface, ensuring that future improvements or bug fixes can be applied without hardware replacement. Overall, the YWBL‑WH infrared CO2 sensor combines reliability, precision, and adaptability, making it a trusted component for scientific research, quality control, and environmental monitoring.

Usage

In laboratory incubators, maintaining a stable CO2 atmosphere is critical for cell culture and tissue engineering. The YWBL‑WH sensor provides continuous, real‑time feedback that can be fed directly into incubator control systems, ensuring that the internal environment remains within the tight tolerance required for optimal biological growth. Its PWM output can drive proportional valves, while the serial interface can log data for long‑term trend analysis.

Beyond incubators, the sensor is well suited for CO2 analyzers used in environmental testing, greenhouse monitoring, and industrial process control. The robust aluminium housing protects the optical components from dust and chemical exposure, while the audible alarm offers an immediate visual cue for operators when concentrations exceed safety limits. The sensor’s low power consumption also makes it attractive for integration into portable monitoring kits used by field technicians who need reliable measurements without the burden of large power supplies.</n

For educational laboratories, the sensor serves as an excellent teaching tool for demonstrating gas sensing principles. Its straightforward wiring and clear output signals allow students to quickly set up experiments that illustrate the relationship between CO2 concentration and biological or chemical processes. The device’s compatibility with common data acquisition platforms further simplifies curriculum development and hands‑on learning.

FAQ

What is the recommended calibration interval for the sensor?

The sensor is factory calibrated and typically maintains its accuracy for up to 12 months under normal laboratory conditions. For critical applications, we recommend performing a verification check every six months and recalibrating if the measured values deviate beyond the specified tolerance.

Can the sensor operate in high‑humidity environments?

Yes, the YWBL‑WH sensor is rated for operation up to 85 % relative humidity. Its internal design includes moisture‑resistant components that prevent condensation from affecting the infrared optical path, ensuring stable performance even in humid incubators.

How does the audible alarm function?

The built‑in audible alarm activates when the CO₂ concentration exceeds a user‑defined threshold. The threshold can be set via the serial interface, allowing integration with existing control software. The alarm provides an immediate audible cue, helping operators respond quickly to out‑of‑range conditions.

Is the sensor compatible with existing data acquisition systems?

Absolutely. The serial output follows standard UART protocols, making it compatible with most data loggers, microcontrollers, and PC‑based acquisition software. Documentation includes command sets and wiring diagrams to simplify integration.

What warranty does the sensor come with?

Each YWBL‑WH sensor is covered by a one‑year limited warranty that protects against manufacturing defects. Should any issues arise within this period, our support team will arrange repair or replacement at no additional cost.
