    De THCO2 is een CO2 concentration sensor, also measuring temperature and humidity. It measures temperatures in the range of -40 to +70 ° C and CO2 concentrations in the range of 0 to 40,000 ppm. It communicates over the RS485 bus by Modbus RTU and Spinel protocols. All with very little consumption. It is designed for measurement in offices, classrooms, training rooms, etc., where it is necessary to monitor the concentration of carbon dioxide (CO2).

    THCO2 is available in interior design, resp. where it is protected from water and condensation moisture.

    The sensor communicates via RS485 using the Spinel or Modbus RTU protocol. It can be on a common communication line with other devices. It is possible to connect 32 devices to one two-wire communication line (more can be). For both protocols, specific communication examples are provided in the documentation.

    The Spinel and Modbus RTU communication protocols can be switched by the ModbusConfigurator software. Modbus can also be easily switched by a jumper on the electronics.

    Examples to use
    Ventilation automation
    Air quality monitoring
    Ventilation to comply with hygienic standards from Decree No. 20/2012 Coll. (maximum CO2 concentration is set at 1500 ppm)

    Features
    Measurement of CO2 concentration in the range of 0 to 40,000 ppm
    Measurement of CO2 concentration by optical NDIR sensor with accuracy ± 30 ppm (see documentation)
    Indication of CO2 concentration by means of an indicator on the device
    Temperature measurement in the range -40 to +70 ° C with an accuracy of ± 0,5 ° C (see documentation)
    Humidity measurement in the range of 0 to 100% RH
    Automatic dew point calculation
    Transfer of measured values directly in ppm, degrees Celsius and percent
    Communication via RS485 line
    Power supply 4.5 to 36 V
    Low power consumption - typically only 8 mA at 12 V
    Spinel or Modbus RTU communication protocols
    Small unobtrusive design - dimensions only 80 × 40 × 20.5 mm (THCO2 label can be peeled off)

    Communication options
    Communication by Spinel or Modbus RTU protocol (default is Spinel, protocols can be switched by software or jumper)
    Easy integration into your systems thanks to complete protocol documentation and implementation of the standard Modbus RTU protocol
    The Spinel.NET library in C # with commented examples in Czech is free for GitHub communication with Spinel.

    Example of reading CO2 concentration, temperature and humidity in Node-RED
    With the Node-RED automation system, you can easily read and process all measured data from THCO2. The following illustration and the source code of the example are a basic example of how to do this.

    Connection of CO2 sensor
    THCO2 sensors are easy to connect to a variety of superior systems. Whether directly to industrial systems with RS485 or via converters to Ethernet, WiFi, USB, RS232, etc.
