Description
>>>Manual: Click here to open<<<Overview: 1. The new T6700 series is a miniature NDIR CO2 sensor that has accuracy and reliability of many larger sensors. The new small size allows OEMs to integrate in to smaller enclosures and equipment and uses significantly less power than many other devices on the market.2. The Telaire T6703 CO2 Module is configured for applications where CO2 levels are less critical but an assessment of indoor air quality is required, for example in residential applications. Our minimum order requirement reflects the high volumes of these applications. 3. All units are factory calibrated to measure CO2 concentration levels up to 5000ppm, while maintaining accuracy across the range.
Features:
- An affordable gas sensing solution for OEMs.- Eliminates the need for calibration in most applications with Telaires patented ABC LogicTM software.- A reliable sensor design based on 20 years of engineering and manufacturing expertise.- Flexible CO2 sensor platform designed to interact with other microprocessor devices.- Compact design and versatile interface options for simple product integration.

Applications:
Air PurifiersAir ConditioningHome monitoringDesktop IAQConsumer product
Interface Connections:
Designed for male header with 0.1 in (2.54mm) spacing Header not included.
Notes:
1. Tolerance based on span gas of ±2%, which adds to the uncertainty, tested at Standard Ambient Temperature and Pressure (SATP).2. Subjecting sensors to environments less than 400 ppm may affect accuracy due to ABC Logic algorithm.3. Based on nominal 5VDC input voltage.For best performance, DC supply should be a regulated, low noise power source.4. Full accuracy to be achieved utilizing ABC Logic. With ABC Logic enabled, the sensor will typically reach its operational accuracy after 24 hours of continuous operation. Sensor will maintain accuracy specifications with ABC Logic enabled, given that it is at least four times in 21 days exposed to a reference level of 400ppm.5. Applies when used in typical residential ambient air.
Calibration:
Does not recommend the customer recalibrate the T6703 module after installation. The sensor ABC Logic algorithm will begin after 24 hours, adjusting the sensor measurement resulting in sensor-to-sensor consistency. If immediate consistency is desired, the sensors may be single point calibrated using pre-mixed reference gas or ambient air measured by a reference sensor.
