Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

2021-07-25· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Create Your Own CO Detector - Digi-Key

CO sensor setup with only a multimeter connected to show output. (Image courtesy of SPEC Sensors) Some needed math: The measurement you can expect is dependent on your setup and the sensor’s sensitivity. In this 2 electrode mode you can expect about half the sensitivity, so if your sensor says nA/ppm, the you can expect about 2 nA/ppm. To convert mV to ppm use Ohm’s law: Voltage (V ...

KNX Presence Sensor: Top 7 List and Automation Guide

2021-06-14· The technology enabling presence or motion sensing can be infrared detection, however the more precise presence detectors also measure brightness, room temperature, humidity, air quality, volatile organic compounds (VOC) and CO2. Presence sensors detect the infrared radiation caused by people present in the room combined with other signs of presence, CO2 being the most obvious.. …

CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, non-occupant-related ...

Monitor CO2 and TVOC With ESP32 : 8 Steps - Instructables

At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas, that must have a specific sensor to monitor it. SGP30 is a gas sensor intended for indoor air quality monitoring. SGP30 can detect a wide range of H2 and return an equivalent carbon dioxide reading calculated based on H2 concentration to the microcontroller over I2C. SGP30 has an ability to set humidity ...
