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...

SKU: AF-992 · MPN: 992

This pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. At 1.5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series, which has up to 0.03 hPa resolution so we don't suggest it as a precision altimeter. Howeve...

SKU: LB-LR0285

The LM35DZ is a simple temperature sensor IC for projects that need low-cost temperature measurement with good accuracy around room temperature.It is suited to remote sensing applications and runs from a broad 4 to 30 V supply range, with very low current drain to help minimise self-heating.Its l...
