CCS811 Gassensor.

CCS811 Air Quality Sensor-DFRobot

The CCS811 air quality sensor supports multiple modes, such as detect in every second, in every 10s, in every one minute, in every 250ms and sleep mode. These modes are optimized for low power consumption during the sensor measurement, so the CCS811 is also suitable for portable applications. NOTE: The chip has stretched the clock in IIC.

ccs811 - Driver for AMS CCS811 digital gas sensor for ...

2021-4-19 · CCS811 supports an external interface for connecting a negative thermal coefficient thermistor (R_NTC) to provide a cost effective and power efficient means of calculating the local ambient temperature. The sensor measures the voltage V_NTC across R_NTC as well as the voltage V_REF across a connected reference resistor (R_REF).

2013-1-8 · The CCS811 offers a sleep mode with wake-up function. By using the active low nWAKE signal connected to a GPIO, power can be saved. If the nWAKE** signal is low, the CCS811 is active and can communicate over I2C. When this signal is high, the CCS811 goes into sleep mode and can't be reached via I2C. The measuring process is not affected.

CCS811 CO2 sensor used as ventilation necessity …

2021-4-21 · Issue Intro We use a CCS811 gas sensor to approximate the aerosol quantity in rooms, which then in turn indicates the potential virus quantity in the air and thus serves as warning if it is necessary to ventilate the room. The problem is that our CCS811 gas sensors return implausibly high co2 values after 2 hours 25 minutes, i.e.: Values above 1.500 ppm, raising up to a maximum value of 2.170 ...
