Teracom TSM400-1-CP 1-Wire carbon dioxide sensor
TSM400-1-CP is a multi-parameter sensor that supports the 1-Wire protocol. The sensor measures the concentration of carbon dioxide and atmospheric pressure. Both basic sensor elements, for carbon dioxide and pressure, used in the device are digital. This ensures high measurement accuracy and longterm stability. The basic sensing element for atmospheric pressure is factory calibrated and it does not require any lifetime recalibration. Automatic calibration is available for carbon dioxide measurements. TSH400-1-CP is housed in a slim plastic enclosure. The bottom part of the enclosure is suitable for installation on standard flush-mounted/cavity wall boxes ø68mm, with installation openings on 61mm.
Features:
• LED indicator for status of communication
• Excellent long-term stability
• Firmware update with Teracom controller via the 1-Wire interface
Applications:
• Environmental quality monitoring and assessment for offices
• CO2 pollution monitoring
• Smart ventilation systems
1-Wire carbon dioxide sensor can be used with:
• Temperature and humidity data logger TCW210-TH
• Ethernet IO module TCW241
• Ethernet data logger TCW220
