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 breakout board is the simplest way to create a project with mutiple capacitive touch sensors. No microcontroller is required here – just power with 1.8 to 5.5VDC and connect up to 5 conductive pads to the 5 left-hand pins. When a capacitive load is detected (e.g. a person touches one of the conductive contacts) the corresponding LED on the right lights up and the output pin goes low. You can use this to update an existing normal-button project where buttons connect to ground when pressed.
This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
The DHT22 (also known by RHT-03) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn t require extra components so you can get right to measuring relative humidity and temperature.
