The CO2, temperature, and humidity sensor supports Modbus-RTU/ASCII RS485 and SDI-12 communication protocols, built-in calibration functionality, and is compact in size, making it widely applicable in greenhouses, cities, poultry farms, transportation stations, and other application scenarios where CO2 level is needed.
Highlighted Features
- 3-in-1 sensor: Measure Carbon dioxide(CO2), air temperature, relative humidity
- Wide Range & High Accuracy of CO2: 0ppm ~ 10,000 ppm, ± (40ppm+3%*MV)
- High performance: high accuracy, fast response, and superior stability
- Wide-range Power Supply and 2 protocols: 5V ~ 24V power supply, support RS485(Modbus -RTU / Modbus -ASCII) and SDI-12 protocols
- User-friendly: factory-calibrated, supports custom calibration by pressing keys or using commands, easy to install and integrate
This is a digital CO2 concentration sensor based on NDIR (nondispersive infrared), which can continuously collect and calculate the CO2 concentration in the air per unit volume and output in the form of a universal interface. It's designed to adopt PTFE film combined with a protective enclosure, improving its breathable performance. It is more accurate, stable, reliable, low-power consumption, and user-friendly. It compacts in size and can be easily integrated into various application scenarios.
This digital NDIR CO2 concentration sensor supports RS485(Modbus -RTU / Modbus -ASCII) and SDI-12 communication protocols and is compatible with the wide power supply voltage of 5-24V. It has a built-in calibration functionality and can be widely applied in both indoor and outdoor environments. This product also adopts both single-air-chamber and double-channel. This CO2 Sensor (Version CO2-Connector) comes with a waterproof aviation connector, helping you save time and effort in wiring the sensor to a data logger with screws.
Application
- Smart Agriculture
- Smart Cities
- Industry and Building ventilation systems
- Airport, train station, shopping mall, home, office, classroom, and others
- public places for air quality measurement and indication
- Lab, warehouse, and other places to monitor the CO2 level
