This kit allows to determine the concentration of CO2 in the air. A microcontroller monitors the measurement and can switch on an alarm or a ventilation system by excessing a threshold. The measurement is carried out of the GassensorTSG4161, which is a further development of the TSG4160. Here, the CO2 concentration is determined in relation to the "natural" air concentration.
Characteristics (using CDM4161 module):
• measures ambient CO2 concentration in air to monitor indoor air quality
• Insensitive to other gases, temperature and humidity
• CO2 concentration measurement range: fresh air (approximately 400 ppm) to 4000 ppm
(0.04 % to 0.4 %)
• Switching output rated for 10 A at 230 V to control ventilation system, with four preset CO2 concentration thresholds
• Switching output rated for 10 A at 230 V to activate alarm or emergency ventilation
• Concentration reading displayed on LCD in digital and analogue form
• Trend indication
• No adjustments required (automatic calibration)
• Simple power supply requirement using mains adaptor
