Product Description
IRceL CH4 NDIR CH4 Sensor Description
Miniature infrared sensor with on-board EEPROM and thermistor
IRceL CH4 NDIR CH4 Sensor Key Features & Benefits:
• Integrated thermistor for accurate temperature compensation
• EEPROM programmed with sensor specfic performance characteristics
• Compact Size
IRceL CH4 NDIR CH4 Sensor Technical Specifications
IMPORTANT NOTE:
Connection should be made via PCB sockets only. Soldering to the pins will seriously damage your sensor.
All performance data is based on conditions at 20°C, 50%RH and 1013mBar, using City Technology recommended circuitry. For sensor performance data under other conditions, refer to the Characterisation Note and Operating Principles.
