SM5870B indoor air quality CO2 sensor for RS485 Bus CO2 sensor, with RS485 interface, standard MODBUS-RTU protocol, enabling simultaneous multi-point monitoring, networking and remote.

Suitable for indoor air quality testing.This product supports secondary development, users simply use any serial communication software module data query and set according to our protocol.A carbon dioxide sensor Korean imports of non-dispersive infrared gas detection technology to detect the concentration of carbon dioxide gas, with high accuracy, long adjustment period, good reproducibility, wide originaluring range, long life, free from other background gas (CH4, H2S, SO2, N2, O2, etc.) affect the advantages.2, the sensor in the design of high-performance single-chip microprocessor and highly integrated digital circuits, simple structure, reliable performance, debugging, and maintenance.Caution:1. Built-in device is a non-dispersive infrared CO2 sensor carbon dioxide sensor, the need for adequate electrical heating to achieve good condition, we recommend that you preheat at least five minutes, even up to 1-3 hours to warm up.2. This product is used for greenhouses, environment, air quality, carbon dioxide detection device control. Suitable for detecting the concentration of carbon dioxide, carbon dioxide gas sensors tested concentration range: 0 -2000ppm.Product Manual Download: http: //sonbest.com/cn/UploadFiles/product/SM5870B.pdf (copy and paste link to download)

SM5870B via RS485 bus networking, communication distance can be extended to up to 1200 meters, the distance can effectively solve the simplest problems connected too short.The figure is based on the RS485 network shown in Figure SM5870B typical sensor monitoring and control of CO2 content value, each SM5870B sensor has a node number, a small system that can be placed 1-15 SM5870B Sensor. Because each SM5870B sensor with wide power supply, so the whole system can be powered using the bus program.
