Carbon Dioxide Sensor PN: RK0801 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...
