High Quality RS485 Carbon Dioxide Temperature and Humidity Sensor, 0-6000ppm Gas Detector, Suitable for HVAC/greenhouse
High Quality RS485 Carbon Dioxide Temperature and Humidity Sensor
Product Introduction:
This product is an intelligent sensor that integrates CO ₂ concentration, temperature, and humidity measurement. It adopts a new infrared calibration technology, which responds quickly and sensitively, completely avoiding the short lifespan and long-term drift problems of traditional electrochemical sensors. The whole machine supports the standard ModBus RTU communication protocol and can be connected to PLC, industrial control computer or various data acquisition systems through RS485 bus. The maximum communication distance is up to 2000 meters, and the communication address and baud rate can be freely set. The networking is flexible and reliable. The equipment is powered by a wide voltage range of 10-30V DC, and the casing has a high level of protection, which can adapt to harsh on-site environments such as agricultural greenhouses, flower cultivation, and edible mushroom cultivation that are humid, dusty, or have large temperature differences.
Core advantages:
- High precision, wide range measurement: CO ₂ default range 0-5000ppm (optional 2000ppm or 10000ppm), high-precision version error is ± (45ppm+3% F · S); Temperature measurement range -40 ℃~+80 ℃, accuracy ± 0.5 ℃; The humidity measurement range is 0-100% RH, with an accuracy of ± 3% RH (25 ℃, 60% RH). Built in temperature compensation mechanism reduces the impact of environmental temperature fluctuations on CO ₂ readings.
- Stable and reliable, well-designed: the system can be used within 2 minutes of preheating and reaches the highest accuracy in 10 minutes; The CO ₂ resolution is as high as 1ppm, and the temperature and humidity resolutions are 0.1 ℃ and 0.1% RH, respectively. The stability is less than 2% F · S, and the nonlinearity is less than 1% F · S. The data is updated every 2 seconds to meet real-time monitoring requirements.
- Convenient installation and debugging: Provides wall mounted waterproof shell and clear wiring identification (brown power positive, black power negative, yellow RS485-A, blue RS485-B), and supports modifying device address and baud rate through ModBus commands to simplify on-site deployment process.
