Product Overview
The RS485 Carbon Monoxide (CO) Sensor is a compact, wall-mounted sensor designed for industrial, environmental, smart-home air-quality, and laboratory monitoring. It measures CO concentrations from 0 to 2,000 ppm while also providing calibrated temperature data. In addition, integrated temperature compensation and low baseline drift help maintain stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and operates on a 5–28 V DC power supply. Moreover, its low-power design, reverse-polarity protection, and built-in surge, TVS, and ESD protection ensure reliable long-term use.
The RS485 Carbon Monoxide CO Sensor is a compact, wall-mounted sensor widely used in industrial processes, environmental monitoring, smart-home air quality systems, and laboratory research. It measures CO concentrations from 0 to 2000 ppm—with a resolution of 10 ppm—and provides calibrated temperature data. Integrated temperature compensation, linear output, and low baseline drift help maintain stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and low-power 5–28 V DC operation. Moreover, its IP50 design, reverse-polarity protection, and built-in surge, TVS, and ESD protection support reliable long-term use. This sensor is available with an RS485 Modbus RTU interface. It is compatible with the SenseCAP S2100 LoRaWAN® Data Logger , enabling low-power, long-range data transmission over LoRaWAN® networks. Note: This sensor is rated IP50 and is designed for indoor environments. It is not suitable for direct outdoor exposure or locations with water ingress risks. Integrated CO and Temperature Monitoring: Measures carbon monoxide concentrations from 0 to 2000 ppm—with a resolution of 10 ppm—and provides calibrated temperature data. Moreover, its T90 response time of less than 35 seconds enables timely detection of concentration changes. Temperature Compensation and Flexible Calibration :Supports both sensor-sensitivity calibration and standard-gas calibration.

Purchasing Guidelines▼
- Full payment is required before an order can proceed to fulfillment and shipment.
- All prices are listed in US dollars (USD) unless otherwise stated.
- Available payment methods are confirmed at checkout and may include bank transfer, supported credit or debit cards, and approved cryptocurrency payments.
- Cryptocurrency and foreign-exchange rates are fixed at the rate applied by the payment provider when payment is successfully processed and confirmed.
- Shipping charges are calculated separately at checkout based on the delivery destination and are not included in the displayed retail price.
- After payment is confirmed, an electronic invoice is issued and made available in the Customer account.
- Hardware orders may be cancelled for a full refund before allocation, custom preparation, packing, or dispatch begins.
- If a bank payment is confirmed after the selected production batch has closed, the Customer may choose the next available batch or request a full refund.
- Approved refunds are initiated within seven business days and are returned through the original payment method, subject to the applicable verification requirements.
Warranty Policy▼
- Eligible hardware purchased directly from {brandname} is covered by a 365-day warranty starting from the date of delivery.
- Warranty coverage is verified through the product serial number and the original sales record.
- Covered faults include verified manufacturing defects, internal component failures not caused by the Customer, delivery damage, and hardware received in a non-operational condition.
- Depending on the technical findings, the resolution may include remote diagnosis, replacement parts, repair, or an equivalent replacement.
- For approved warranty repairs, {brandname} covers standard return shipping after the repair or replacement is completed.
- The Customer is responsible for shipping an authorized warranty return to the service location specified in the RMA case.
- Unauthorized firmware, third-party overclocking, or unsupported modifications may affect warranty coverage only where they caused the fault or prevent reliable diagnosis.
- Damage caused by improper electrical installation, power surges, liquid exposure, inadequate cooling, operation outside specified environmental limits, or tampering with the serial number may be excluded from warranty coverage.
- Covered repairs are targeted for completion within 10 business days after receipt at the authorized service location. If additional time is required, the Customer will receive a written update or an alternative resolution plan.
