The GP2Y0A41SK0F Sharp analog distance sensor features a detection range of 1.5 to 12 (4 cm to 30 cm). The shorter range gives you higher resolution measurements, and the lower minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.
This semiconductor gas sensor detects the presence of LPG, isobutane, and propane at concentrations from 300 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
This is the T5403 breakout board, a fully calibrated barometric pressure sensor with an I2C interface. The T5403 sensor measures the absolute pressure of the air around. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the weather, measure altitude, or any other tasks that require an accurate pressure reading.
This semiconductor gas sensor detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
This breakout board is the simplest way to create a project with a single “momentary” capacitive touch sensor. No microcontroller is required here – just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn’t suited to your project.
