Overview
The CCS811B-JOPD500 is a digital air-quality sensor from ScioSense with an I2C interface for easy integration. It is intended for indoor air-quality monitoring and reports air-quality metrics over I2C while operating from a 1.8 V to 3.6 V supply. The device is specified with a typical supply current of about 26 mA and an operating temperature range of -5 C to 50 C.
Why Choose This Part
The CCS811B offers a simple digital I2C interface that reduces integration complexity compared with analog gas sensors. Its low-voltage supply range (1.8 V to 3.6 V) makes it compatible with many microcontrollers and battery-powered designs. The specified supply current (~26 mA) and compact package make it suitable for embedded consumer and IoT products where board area and power budget are constrained.
Applications
Key Specifications
Getting Started
Connect the sensor to an I2C host and observe the supply voltage limits (1.8 V to 3.6 V); use level shifting if your host runs above 3.6 V. Provide proper decoupling on the supply pins, follow the datasheet for any required startup or calibration sequence, and check for available Arduino or Raspberry Pi libraries and example code for the CCS811 family to accelerate evaluation.
