Back to the design description, the D13 signal output pin (TP4), which is logic-low (L) by default, shifts to a logic-high (H) state for a while when an object appears within sight of the infrared ...

When an object comes within the sensor's range, the amount of reflected light changes, causing the sensor’s output to switch state. Arduino Processing: The Arduino reads the output from the IR sensor.

The IR Detector proximity sensor has launched via Kickstarter and is now available to back from just $5 with worldwide delivery expected to take place during February 2019.

Arduino has launched the MKR IoT Carrier Rev2 board for Arduino MKR boards with a Bosch SensorTech BME688 4-in-1 pressure, humidity, temperature, and gas sensor replacing the HTS221 humidity sensor ...
