Once the WiFi library is installed on the Arduino IDE, you can now add the header in code. #include Define SSID and password values for your WiFi point: const char* ssid = "YOUR_NETWORK_SSID";const char* password = "YOUR_PASSWORD"; Optionally, with setup() function we start a conn...
Updated and improved Arduino library for the MQ135 gas/air quality sensor. This library is also available in the Arduino IDE, seeArduino Library List. Datasheet Can be foundhere. Application This type of sensor is used in air quality control equipments for buildings/offices and is suitable for...
Code Issues Pull requests We present a unified library for MQ sensors, this library allows to read MQ signals easily from Arduino, Genuino, ESP8266, ESP-32 boards whose references are MQ2, MQ3, MQ4, MQ5, MQ6, MQ7, MQ8, MQ9, MQ131, MQ135, MQ136, MQ303A, MQ309A. arduino ...
For testing purpose we need serial monitor, once your calibration is complete, you can power arduino from external power sources. Don’t use batteries as main supply, it draws few hundred mA from the supply, when the sensor goes below optimum temperature, it gives false alert. However, you ...
