Product description: SenseCAP SOLO CO2 5000 - CO2 concentration sensor - NDIR - MODBUS-RTU RS485 and SDI-12 - Seeedstudio 101990669
DigitalCO2 concentration sensor, which operates on the basis of non-dispersive NDIR technology. A non-dispersive sensor, which means that there is no element that splits light into its components. The measuring range is from 400 ppm to 5000 ppm. The module supports Modbus (Modbus-RTU / Modbus-ASCII) RS485 and SDI-12communication protocols, has built-in calibration and compact dimensions. It can be used for indoor and outdoor environment. It is used in agriculture, greenhouses, industrial ventilation systems or transport stations, as well as in projects that require the determination of CO2 levels.
Digital CO2 sensor from Seeedstudio.
Mounting screws are included.Features
- High performance: accuracy, fast response and excellent stability
