Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.
The A1301is a continuous-time, ratiometric, linear hall effect sensor. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.
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.
This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 1,000 ppm and combustible gas from 100 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
The LM35CZ is an analog temperature sensor which has a measurement range of -40 to +110 Degree C.
