Digital NDIR Carbon dioxide CO2 Sensor Module

Product Overview

Description

NDIR CO2 Sensor Module

 

 

 

Description
RK0801 NDIR infrared gas small size sensor, using non principle to detect the existence of CO2 selectivity, non-oxygen dependent and long temperature compensation; and it has UART output and PWM output. It is developed by the mature infrared absorbing gas detection technology, precision optical circuit design.

Features
Chamber is gold plated, water- proof and anti-corrosion
High sensitivity, low power consumption
Temperature compensation, excellent linear output
Multiple output modes: UART, PWM

Main Application
HVAC refrigeration,
Air cleaner,
Indoor Air quality monitoring,
Smart home,
Ventilation system.

 

 

 

 

 

 

Cautions:

1. Please avoid the pressure of its gilded plastic chamber from any direction, during welding, installation, and use.

2. When placed in small space, the space should be well ventilated, especially for diffusion window.

3. The sensor should be away from heat, and avoid direct sunlight or other heat radiation.

4. The sensor should be calibrated termly, the suggested period is not longer than 6 months.

5. Do not use the sensor in the high dusty environment for long time.

6. To ensure the normal work, the power supply must be among 4.5V~5.5V DC rang, the power current must be not less than 150mA. Out of this range, it will result in the failure of the sensor. (The concentration output is low, or the sensor can not work normally.)

7. During the zero point calibration procedure by manual, the sensor must work in stable gas environment (400ppm) for more than 20 minutes. Connect the CAL pin to low level (0V) for over 7 seconds.

8. Forbid using wave soldering for the sensor.

9. When soldering with soldering iron, set the temperature to be under 350°C, and soldering time must be within 3 seconds.

10. As for pin version sensor, it is recommended to use soldering socket to directly insert or remove sensors for convenient maintenance.
