7Semi CO2, Temperature & Humidity Sensor Probe I2C 400-5000 PPM

The 7Semi CO2, Temperature & Humidity Sensor Probe I2C (400–5000 PPM) is a compact, high-accuracy environmental sensing module designed to measure carbon dioxide concentration, ambient temperature, and relative humidity simultaneously. It uses an advanced NDIR (Non-Dispersive Infrared) CO2 sensing principle combined with digital humidity and temperature sensors for precise and reliable readings. The probe communicates via the I²C interface, providing fully calibrated digital outputs and requiring no external components. Its durable probe design makes it suitable for indoor air quality monitoring, HVAC control, and smart IoT applications.
