The SCD30 is a compact air quality sensor module that simultaneously measures CO2, relative humidity, and temperature. It delivers reliable environmental data in a single device, simplifying sensor design and reducing component count. Key benefits - Easy integration: I2C interface enables straightforward, reliable communication with most microcontrollers and SBCs. - Network readiness: Modbus support allows seamless data exchange and remote monitoring in Modbus-based networks. - Actuation ready: PWM1 output lets you drive external devices (fans, dampers, alarms) based on real-time air quality readings. - Compact, robust: Small form factor designed for embedded systems with consistent, repeatable measurements. What it solves - Reduces sensor hardware by combining three measurements into one module. - Enables cross-device data sharing and centralized monitoring. - Facilitates automation and alerts by enabling external device control from air quality data. Use scenarios - Smart buildings: maintain healthy indoor air by linking CO2, humidity, and temperature to HVAC and ventilation controls. - Office or classroom IAQ: monitor the environment and trigger alerts or automatic adjustments when thresholds are reached. - Greenhouses and labs: log environmental data and automate fans or humidification to maintain optimal conditions. Notes - For data reads, use the I2C interface; for networked systems, leverage Modbus; use PWM1 to actuate connected devices.
