• Small footprint NDIR Sensor
• Designed for long-term battery operation
• Variable measurement period to save energy
The LP8 miniature CO2 sensor is one of the smallest, lowest-power, non-dispersive infrared (NDIR) sensor on the market today. It was designed from the ground up for long-term battery or solar-powered applications. It gives full control for integration into a host system, and a flexible CO2 measurement period to minimize power consumption in the field. One measurement requires only 3.6 mC of charge (or energy 11.9 mJ having 3.3V on the battery).
A wide supply voltage range (2.9-5.5V) enables a variety of battery options for powering the sensor. For example it can be powered by 3 alkaline 1.5V batteries, or a single 3.6V Li-SOCl2 battery for a more compact alternative.
The LP8 provides a relatively simple communication protocol which lets you change the measurement period, compensate for barometric pressure, and control calibration in real time. Background (ABC) and zero-gas calibrations methods are both implemented in a simple manner.
