This infrared obstacle/object detection sensor is super easy to use. It comes with a potentiometer to adjust the sensitivity. The output is a digital signal so it is easy to interface with any microcontroller such as Maker UNO, Mega, Leornado, Zero, 101, or even the Raspberry Pi or Raspberry Pi Zero.

Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This plastic dongle plugs between a USB device, and passes the data lines through.

Use this kit as inputs for sensing and outputs for reporting in your projects. Compatible with all models of Arduino and Raspberry Pi

These header pin blocks use the industry standard spacing of 2.54mm. Ideal for Pi ZERO

This digital temperature and humidity module is a digital output signal containing a calibrated temperature and humidity combined sensor.
