The Grove-VOC and eCO2 Gas Sensor SGP30 is an air quality sensor (Arduino compatible). Based on SGP30, this module provides TVOC (Total Volatile Organic Compounds) and CO2eq output with outstanding long-term stability and low power consumption, which make it a perfect choice for indoor air quality detection. Email.
By knowing the exact concentration of CO2, we can do something to reduce the atmosphere's CO2 level and to protect our earth. For that reason, DFRobot eningeer's designed a high quality CO2 sensor. This is the first CO2 sensor on the opensource hardware market. The output voltage of the module falls as the concentration of the CO2 increases.
The following parameters were accounted in this project: Perfect room temperature lies between 18 and 22 °C (according to WHO organisation); Optimal humidity level for health and eye comfort is minimum 40%; Concentration of CO2 should be smaller than 1, 000ppm; Level of the luminosity for eye comfort should be >500KΩ.
Next, connect a 4-wire Grove cable to the Grove OLED screen. Plug the other side into the shield on the port labeled I2C_1. Connect another 4-wire Grove cable to the BME280 temperature and humidity sensor. Plug the other side into the shield on the port labeled I2C_2. Next, connect another 4-wire Grove cable to the Air Quality sensor.
Feb 19, 2021· La console semble correcte (à 115200 bauds) puisque l’on voit le message d’invite et les premiers résultats. Le code d’exemple de lecture de la réponse du capteur est assez mauvais - si le capteur n’a pas fini de répondre en 10ms ça peut afficher n’importe quoi (mais vous ne devriez quand même pas voir de hiéroglyphes).
1. Connect the module to the Analog port 0 of Grove - Basic Shield using the 4-pin grove cable. Connect Buzzer to Pin 3. 2. Plug the Grove - Basic Shield into Arduino. And connect Arduino to PC by using a USB cable. 3. Copy and paste the code below to a new Arduino sketch. Please read this if you do not know how to upload.
The Grove - SCD30 is a 3-in-1 Arduino sensor that can measure CO2, temperature, and humidity. B ased on Sensirion SCD30, it is a Non-Dispersive Infrared(NDIR) carbon dioxide sensor with high precision and wide measurement accuracy. It would be a perfect choice if you are looking for a multifunctional sensor for your Arduino weather station or other environmental projects.
Jun 18, 2020· Le site Web de Seeed propose un wiki et une section Projects, et leur Github est rempli de codes Arduino et d'autres fichiers à utiliser avec les modules Grove. Essayer différents modules avec les exemples de codes Capteur de son. Le capteur de son est l'une des démonstrations fournies avec le Starter Kit.
Step 1 : Embedded Arduino grove sensor. In order to understand the sensor capacity on citizen understanding, a first device has been made with arduino Grove. Using a shield and 3 sensors (temperature, indoor air quality and outdoor quality), the workshop aimed at understanding the factor of data appropriation by children and public.

Jul 20, 2019· In this project, we recorded CO2 and O2 data from six Sensirion SCD30 and Grove-ME2-O2 sensors using Arduino MEGA. While the ME2-O2 produce analog output, the SCD30 communicate via the I2C interface. Each SCD30 sensor has the same permanent I2C address, therefore, we use TCA9548A I2C multiplexer to read multiple SCD30.
