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.
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.
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 breakout board is the simplest way to create a project with a single “toggle” capacitive touch sensor. No microcontroller is required here – just power with 1.8 to 5.5VDC and touch the pad to activate the sensor.
