PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

Microwave radar sensor can detect distance by transmitting and receiving radio wave. Compared with range&distance sensor of other kinds, the radar sensor can provide...

The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature.

We've all been there. That thing is close but how close? When you need to measure a meter-or-so distance with reasonable accuracy, the VCNL4200 Long...

The VCNL4010 sensor is a nice way to add a small-distance proximity sensor to your microcontroller project. For longer distances (in the range of cm, you can use...

MW0582TR11 - 5.8GHz Microwave Doppler Radar Motion Sensor is a microwave Doppler radar that has a frequency of 5.8GHz. This microwave sensor has high...

This microwave sensor is a microwave module that can transmit the electromagnetic wave of 5.8GHz. It can detect the difference between the transmitted...

Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.

The 80cm Infrared Proximity Sensor is a General Purpose Type Distance Measuring Sensors, this sensor takes a continuous distance reading and returns a...

This extra-long-range SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine...

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.
