The recommended operating temperature range for the NDIR08ST is -20°C to 70°C. However, it's essential to note that the device can tolerate storage temperatures between -40°C and 85°C.
APEM Inc recommends calibrating the NDIR08ST in a controlled environment with a known CO2 concentration. It's essential to follow the calibration procedure outlined in the datasheet and to recalibrate the device periodically to maintain accuracy.
The response time of the NDIR08ST is typically around 2-3 minutes. This means that the device takes around 2-3 minutes to stabilize and provide accurate CO2 readings. Engineers should consider this response time when designing their application, especially in scenarios where rapid CO2 changes are expected.
While the NDIR08ST is designed to operate in various environments, it's essential to take precautions when using it in humid or dusty conditions. APEM Inc recommends using a protective enclosure or applying a conformal coating to prevent moisture or dust ingress, which can affect the device's performance and accuracy.
The NDIR08ST communicates via an analog output (0-5V) or an optional UART interface. Engineers can interface the device with their microcontroller or other devices using these interfaces. APEM Inc provides example code and documentation to facilitate integration.
