Wall Mount CO2 Transmitter

=Real-time air quality/CO2 detection with flexible connectivity for both new and existing building networks. It features an optional temperature and humidity sensor, with an OLED display providing real-time data. Equipped with one or two analog outputs configurable for linear or PID control, it monitors CO2 levels alone or alongside temperature. A relay output with dual control modes and a Modbus RS485 interface allow seamless integration with BAS or HVAC systems. An audible buzzer and relay-triggered alarm enhance safety by alerting and managing connected devices effectively. Real-time monitoring of CO₂ Wireless cloud connectivity with optional RS485 or WiFi interface Compatible with both new and existing building networks Wall-mountable with 24VAC/VDC power supply Optional temperature & humidity monitoring with OLED display Backed by 14+ years of global IAQ experience Specifications Output RS485 or WIFI RJ45 (Ethernet TCP) MQTT protocol, Modbus customization or Modbus TCP optional WiFi@2.4 GHz 802.11b/g/n MQTT protocol, Modbus customization or Modbus TCP optional Data upload interval cycle Average / 60 seconds Operating Environment Temperature：0~50℃    Humidity︰0~99%RH Storage condition -10℃~50℃      Humidity︰0~70%RH (No condensation) Power supply 24VAC±10%, or 18~24VDC Overall Dimension 94mm(L)×116.5mm(W)×36mm(H) Material of Shell & IP Level PC/ABS fire-proof material / IP30 Installation Concealed installation: 65mm×65mm wire box CO2  Sensor Non-Dispersive Infrared Detector (NDIR) Measuring Range 400～2,000ppm Output Resolution 1ppm Accuracy ±75ppm or 10% of reading Temperature and Humidity (optional) Sensor Digital integrated temperature and humidity sensor Measuring Range Temperature: -20℃~60℃   Humidity: 0~99%RH Output Resolution Temperature: 0.01℃   Humidity: 0.01%RH Accuracy Temperature: ≤±0.6℃@25℃ Humidity: ≤±3.5%RH （20%~80%RH）   Downloads Wall Mount CO2 Transmitter Datasheet
