SenseCAP CO2 Sensor
Product Description
This is a digital CO2 concentration sensor based on NDIR (nondispersive infrared), which can continuously collect and calculate the CO2 concentration in the air per unit volume and output in the form of a universal interface. It's designed to adopt PTFE film combined with a protective enclosure, improving its breathable performance. It is more accurate, stable, reliable, low-power consumption, and user-friendly. It compacts in size and can be easily integrated into various application scenarios.
This digital NDIR CO2 concentration sensor supports MODBUS RS485 serial communications, SDI-12 communication protocols, and is compatible with the wide power supply voltage of 5-16V. It has a built-in calibration functionality and can be widely applied in both indoor and outdoor environments. This product also adopts both single-air-chamber and double-channel.
