This is IOT Based Air Pollution Monitoring System that measures indoor harmful gases present in the air like Carbon Dioxide(CO2) using an MQ135 gas sensor and Carbon Monoxide(CO) using an MQ7 sensor. It will show the air quality in PPM(Parts Per Million) on the LCD and as well as on Thingspeak so that we can monitor it very easily in PPM.
Projects and libraries code for the Pic 16F18446 Microcontroller ( 8-bit, 20-pin).
A project to use MQ7 / MQ2 sensors along with uMQTT for tracking gas levels. Implemented on Pycom FiPy/WiPy esp32 micropython microcontroller. MQTT and push notification on phone implemented.
IoT - Low cost Air Quality sensor using esp32, mq-7, mq-131, pms5003
A project that includes Arduino code for getting the air quality sensors readings and sends it to Raspberry-based server.
