Bonjour a tous, Bonne santé et année 2022.
Pour ceux que le sujet intéresse je vous invite a suivre la calibration de mon capteur de Co2 sur ThingSpeak depuis 13h05 : SCD30 - ThingSpeak IoT <https://thingspeak.com/channels/1628404> Voici le code source sous arduino pour donner une idée : // Basic demo for readings from Adafruit SCD30 #include <Adafruit_SCD30.h> #include "ThingSpeak.h" #include <WiFi.h> #include "ccs811.h" // CCS811 library #include <TFT_eSPI.h> #include <SPI.h> char ssid[] = "iot_1"; // your network SSID (name) char pass[] = "password1234"; // your network password int keyIndex = 0; // your network key Index number (needed only for WEP) WiFiClient client; // Timer variables unsigned long lastTime = 0; unsigned long timerDelay = 30000; unsigned long myChannelNumber = 00000; const char * myWriteAPIKey = "xxxxxxx"; Adafruit_SCD30 scd30; void setup(void) { Serial.begin(115200); while (!Serial) delay(10); // will pause Zero, Leonardo, etc until serial console opens Serial.println("Adafruit SCD30 test!"); // Try to initialize! if (!scd30.begin()) { Serial.println("Failed to find SCD30 chip"); while (1) { delay(10); } } Serial.println("SCD30 Found!"); // if (!scd30.setMeasurementInterval(10)){ // Serial.println("Failed to set measurement interval"); // while(1){ delay(10);} // } Serial.print("Measurement Interval: "); Serial.print(scd30.getMeasurementInterval()); Serial.println(" seconds"); WiFi.mode(WIFI_STA); ThingSpeak.begin(client); // Initialize ThingSpeak Serial.print("I2C port > SDA: "); Serial.print(SDA);Serial.print(" SCL: "); Serial.println(SCL); } void loop() { if (scd30.dataReady()){ Serial.println("SCD30 Data available!"); if (!scd30.read()){ Serial.println("Error reading sensor data"); return; } // Connect or reconnect to WiFi if (WiFi.status() != WL_CONNECTED) { Serial.print("Attempting to connect to SSID: "); //Serial.println(SECRET_SSID); while (WiFi.status() != WL_CONNECTED) { WiFi.begin(ssid, pass); // Connect to WPA/WPA2 network. Change this line if using open or WEP network Serial.print("."); delay(5000); } Serial.println("\n Wifi Connected."); } Serial.print("Temperature: "); Serial.print(scd30.temperature); Serial.print(" degrees C |"); Serial.print("Relative Humidity: "); Serial.print(scd30.relative_humidity); Serial.print(" % |"); Serial.print("CO2: "); Serial.print(scd30.CO2, 3); Serial.println(" ppm"); Serial.println(""); // ComputeAvgVelues(); // PublishOnThingSpeak(); //void PublishOnThingSpeak( ) // set the fields with the values ThingSpeak.setField(1, scd30.CO2); ThingSpeak.setField(2, scd30.relative_humidity); ThingSpeak.setField(3, scd30.temperature); // ThingSpeak.setField(4, humidity); // ThingSpeak.setField(5, pressure); // ThingSpeak.setField(6, ppm); // Write to ThingSpeak. There are up to 8 fields in a channel, allowing you to store up to 8 different // pieces of information in a channel. Here, we write to field 1. int x = ThingSpeak.writeFields(myChannelNumber, myWriteAPIKey); if (x == 200) { Serial.println("Channel update successful."); } else { Serial.println("Problem updating channel. HTTP error code " + String(x)); } delay(15000); } } Bon weekend a tous Richard Le dim. 26 déc. 2021 à 18:33, Raphaël Jacquot <sxp...@sxpert.org> a écrit : > > > Le 24/12/2021 à 16:00, guilla...@ophane.net a écrit : > > On 23/12/2021 10:38, Remi Desgrange wrote: > >> Au bureau, on a des capteurs dans les open spaces qui fonctionne bien. > Un > >> petit lien avec les détails : > >> > >> > https://www.camptocamp.com/en/news-events/how-open-source-contribute-to-safer-offices > >> > >> > > > > CH2O aussi fait mal à la tête -_^ (SFA30). > > > > tu confonds très certainement avec C2H5OH... > > > --------------------------- > Liste de diffusion du FRnOG > http://www.frnog.org/ > --------------------------- Liste de diffusion du FRnOG http://www.frnog.org/
