MQ4 Methane Gas Sensor : Pinout, Interfacing with Arduino ...

The analog pin of the sensor then generates an analog signal proportional to the amount of CH4 in the air. We can measure the analog output of a sensor with an ADC microcontroller. Nowadays most microcontrollers come with a built-in ADC peripheral which can be used to read the analog output of such sensors such as MQ4. Microcontroller reads the analog output signal of the methane gas sensor ...

Passive Infrared Sensor — ESPHome

You need to connect GND to a GND pin on your board and VCC to a 5V or 12V pin. Technically you can also connect VCC to , but the sensor measurements won’t be as stable. Next you need to connect the signal pin (OUT). Fortunately, the sensor signal has a voltage of max, so we can directly connect it to a free GPIO pin on the ESP board. Otherwise, we would need to step down the voltage ...

Pololu - Adding a Zumo reflectance sensor array ...

The shield uses one digital I/O pin for each sensor (5, A2, A0, 11, A3, and 4), and if you add the LEDON shorting block, one additional pin (either A4 or 2) is used. To configure the ZumoReflectanceSensorArray object to use this default pinout, simply call init with no arguments: (); If you opt to leave off the LEDON shorting block, you should use the QTR_NO_EMITTER_PIN ...

Touch sensor objects - Microsoft MakeCode

Sensor objects. Connecting an object to a touch pin can make it touch sensor. The pin can adjust the way it measures the electrical effect of adding some more conductive surface to the pin. When some object is connected to a pin, it changes the capacitance that is measured for the pin. When your program starts, it calibrates its measurement of ...

Pololu - 3. QTRSensors Methods & Usage Notes

This pin is optional and does not exist on some of the QTR sensor arrays. If a valid pin is specified, the emitters will only be turned on during a reading. If the value QTR_NO_EMITTER_PIN (255) is used, you can leave the emitter pin disconnected and the IR emitters will always be on. Constructor: QTRDimmableRC() This version of the constructor performs no initialization. If it is used, the ...

HLW8012 Power Sensor — ESPHome

This sensor has two data outputs which both encode values using the frequency of a modulated signal: CF and CF1. CF’s frequency is proportional to the (active) power measured and CF1 is proportional to the current/voltage. Using the SEL pin, one can choose between which mode to use. ESPHome will continuously cycle the state of the SEL pin to measure current and voltage, though both cannot be ...
