Low Power Low Profile Carbon Dioxide Sensor NDIR CO2 Sensor Description
The CozIR®-LP3 CO sensor uses proprietary solid-state LED technology to achieve unrivalled low-power consumption, making it suitable for a range of applications including battery-powered and wirelessly connected devices.
The CozIR®-LP3 provides the user with extensive flexibility, a choice of UART or I²C control interfaces, digital and analogue CO measurements, and a fail-safe digital alarm level monitor.
The CozIR®-LP3 includes on-board power management, allowing the user to control sensor power consumption during measurements and when the sensor is inactive. The user can reduce active current consumption to <1µA without switching o the sensor.
The low height form factor, small footprint and flexible mounting options make the CozIR®-LP3 ideal for applications where space is at a premium.
The CozIR®-LP3 is designed to run fully autonomously with automatic self-checking and auto-zeroing, enabling the sensor to operate for long periods with no user intervention.
