Senseair S8 LP - CO2 Sensor

Senseair S8 LP is a miniature, low-power CO2 sensor module developed for applications where both energy consumption and accuracy are critical factors. With an average power consumption of 18 mA and an accuracy of ± 40 ppm and ± 3% of reading, the S8 LP is the natural choice for developers who demand the best of two worlds. S8 LP is a module that is designed for simple integration into products. S8 LP can be used in a wide range of applications such as in ventilation control to improve energy savings and to assure a good indoor climate.

This sensor provides a UART Modbus interface that can be used to get CO2 readings with Arduino, Tasmota, ESPHome, ESPEasy etc. Alternatively there is a PWM output or an alarm output that triggers at 1000ppm.
