Ikea vindriktning-air-quality

[markusvankempen]

I have been working with Ikea vindriktning senor using tasmota and adding a wemos +bme680 . I think it it would be a great addition to the sensor lib to add the cheap ikea pm2.5 sensor

https://www.ikea.com/ca/en/p/vindriktning-air-quality-sensor-60515911/ here a example tuturial https://blakadder.com/vindriktning-tasmota/

We need first know what library they are using, and test it. Maybe you can send me a simple Arduino hello world running over your stuff? then I could include it

Hello @hpsaturn take a look at https://github.com/Hypfer/esp8266-vindriktning-particle-sensor

output example: 11:14:35.250 -> Receiving:....................Done. 11:14:35.547 -> Received PM 2.5 reading: 26 11:14:35.547 -> Current measurements: 25, 25, 26, 25, 25 11:14:37.548 -> We have a PM2.5 state

here a simple code: / Ikea - vindriktning /

include "SerialCom.h"

include "Types.h"

particleSensorState_t state;

// the setup function runs once when you press reset or power the board void setup() {

// initialize digital pin LED_BUILTIN as an output. pinMode(LED_BUILTIN, OUTPUT);

  Serial.begin(115200);
SerialCom::setup();

Serial.println("\n");
Serial.println("Hello from  vindriktning-particle-sensor");
Serial.printf("Core Version: %s\n", ESP.getCoreVersion().c_str());
Serial.printf("Boot Version: %u\n", ESP.getBootVersion());
Serial.printf("Boot Mode: %u\n", ESP.getBootMode());
Serial.printf("CPU Frequency: %u MHz\n", ESP.getCpuFreqMHz());
Serial.printf("Reset reason: %s\n", ESP.getResetReason().c_str());

delay(3000);

}

// the loop function runs over and over again forever void loop() { SerialCom::handleUart(state); digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second

if (state.valid) { printf("We have a PM2.5 state\n"); Serial.print(state.avgPM25); printf("\n"); }else{ printf("No PM2.5 state\n"); }

}

Good. Sound likes that it will be easy. One question. What stuff can you use? TTGO T-Display? My question is for understand the possible pins for a initial test

[hpsaturn]

good news! @roberbike from our community in Telegram, he test it and it works fine! Thanks to both of you for your feedback and tests. We will be a new version soon:

I'm going to close this issue. The last version of CanAirIO firmware already has this support. Thanks!
