It measures carbon dioxide concentration over a range of 0 to 500 ppm and simultaneously captures ambient temperature data, providing dual-parameter readings from a single device. Output signals are available in both voltage and current formats, and the unit supports a relay option for direct control integration. Installation is handled by licensed HVAC controls technicians or building automation system integrators as part of an IAQ or HVAC monitoring loop.\u003c\/p\u003e\n\u003cp\u003eThe CT1R-A3D is well suited for applications where air quality and temperature data must be continuously tracked and acted upon. Supported application environments include greenhouses, laboratories, food and beverage facilities, general IAQ projects, parking garages, agricultural facilities, and transportation environments. The recessed wall-mount form factor allows flush or near-flush installation in finished wall surfaces, making it appropriate for occupied spaces where aesthetics and sensor protection both matter. The onboard display provides local readout without requiring a separate handheld instrument.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCO2 measurement range of 0 to 500 ppm for low-concentration monitoring applications\u003c\/li\u003e\n  \u003cli\u003eSimultaneous CO2 and temperature sensing in a single wall-mount enclosure\u003c\/li\u003e\n  \u003cli\u003eVoltage and current output signal options for flexible BAS and controller integration\u003c\/li\u003e\n  \u003cli\u003eOptional relay output for direct equipment control or alarm triggering\u003c\/li\u003e\n  \u003cli\u003eIntegrated display provides local real-time readout without additional equipment\u003c\/li\u003e\n  \u003cli\u003eRecessed wall-mount design suits occupied spaces requiring a clean, low-profile installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install room CO2 and temperature sensor compatible with building automation systems and HVAC controllers that accept standard voltage or current analog input signals.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC controls technician or building automation system integrator familiar with low-voltage analog wiring practices. De-energize the control circuit at the panel before wiring the sensor outputs. Follow applicable NEC guidelines for low-voltage signal wiring, and verify that the controller input type matches the selected output signal format (voltage or current) before powering the system. Locate the sensor away from supply air diffusers, direct sunlight, and heat-generating equipment to ensure accurate ambient readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range (CO2)\u003c\/strong\u003e: 0 to 500 ppm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Signal\u003c\/strong\u003e: Voltage, Current\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptions\u003c\/strong\u003e: Relay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e: Wall (Recessed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Greenhouse, Laboratory, Food and Beverage, IAQ, Parking Garage, Agricultural, Transportation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SENVA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CT1R-A3D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SENVA","offers":[{"title":"Default Title","offer_id":51284128071986,"sku":"CT1R-A3D","price":375.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279102.jpg?v=1781069262","url":"https:\/\/voomisupply.com\/products\/senva-ct1r-a3d-recessed-wall-co2-temperature-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
