Connecting LP8 CO2 Sensor to Arduino


Our engineers have written a new application note titled: AN162: Connecting the LP8 CO2 Sensor to an Arduino via UART.

This document allows you to talk to SenseAir's LP8 miniature CO2 sensor with an Arduino Uno, Mega or Mega2560 microcontroller using a UART TXT-RXD connection. The example Arduino code uses Software.Serial, a library built into the Arduino software.

The LP8 sensor is primarily intended for battery applications. While it can take a measurement as often as every 16 seconds, frequent measurements will decrease battery life. Therefore, the code shows how to put the sensor to sleep between measurements.
