Its response is cross-sensitive, so it does not uniquely identify which gas is present.\u003c\/p\u003e\n\u003ch3\u003eDoes this module provide a digital reading?\u003c\/h3\u003e\n\u003cp\u003eNo. This version provides an analog A0 output. Your microcontroller needs an ADC input, or an external ADC if the board has no analog input.\u003c\/p\u003e\n\u003ch3\u003eCan I power it from 3.3V?\u003c\/h3\u003e\n\u003cp\u003eThe sensor module is specified for approximately 5V operation. Use a proper 5V supply and make sure the analog output voltage is safe for a 3.3V ADC before connecting it.\u003c\/p\u003e\n\u003ch3\u003eDoes it require warm-up and calibration?\u003c\/h3\u003e\n\u003cp\u003eYes. MEMS metal-oxide gas sensors require warm-up, baseline measurement and calibration for meaningful concentration estimates. Temperature, humidity and interfering gases can affect readings.\u003c\/p\u003e\n\u003ch3\u003eCan it be used as a home CO alarm?\u003c\/h3\u003e\n\u003cp\u003eNo. It is a development module and should not replace a certified carbon-monoxide or gas alarm.\u003c\/p\u003e\n\u003ch3\u003eIs it compatible with Arduino, ESP32 and Raspberry Pi Pico?\u003c\/h3\u003e\n\u003cp\u003eYes, when powered correctly and connected to an appropriate analog input. For 3.3V controllers, protect the ADC input if the module output can exceed the controller's limit.\u003c\/p\u003e\n\u003ch3\u003eIs delivery available across Pakistan?\u003c\/h3\u003e\n\u003cp\u003eYes.
