7Semi CO2 Temperature Humidity Sensor Probe 400–5000 PPM I2C

A 3-in-1 probe that reads CO2 (400–5000 ppm), temperature and relative humidity from a single factory-calibrated sensor over I2C. A waterproof metal housing on a 1-metre cable lets the sensing tip sit in a duct or room space while the rest of the circuit stays protected.

• CO2 range: 400–5000 ppm, plus temp and RH
• Factory-calibrated digital output over I2C
• Waterproof metal probe housing, 1m cable
• Suited to HVAC and indoor air-quality builds

Fits neatly into a classroom air-quality monitor, a smart-building automation project, or a greenhouse controller where CO2 levels matter as much as temperature and humidity.
