Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a...

Infrared break-beam sensors are a simple way to detect motion. This IR break beam sensor works up to 50cm with a fast and stable response of

The QTR-1A reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following. The reflectance measurement is output as an analog voltage. This sensor is sold in packs of two units.

Add an easy to use end-stop sensor or filament run-out sensor to your printer/project!

This IR break beam sensor works up to 4m with a fast and stable response of 0.5ms. Power the sensor by a voltage of DC 5V. It can be used with Arduino in...

This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 10mm

This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This high-brightness version draws an average of 16 mA at 5 V and has a typical sensing range up to approximately 24 inches (60 cm).

This adjustable infrared sensor features a high-sensitivity photoreflector to perform distance detection function,ranging from 3cm to 50cm. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation.

This is a photoelectric switch that is composed of emitter and receptor.The emitter consists of a laser diode,and the laser has the characteristics of high precision, good orientation etc.The receptor consists of a photoelectric element.When receiving the laser pulse, the built-in light conducting.The emitter and receptor can assemble a detector. It can be directly compatible with Arduino to develop related products .Of course,it is also very suitable for photoelectric counting, security, ultra-high vehicle overrun detection etc.

This is a pair of photoelectric switches with a detection distance of up to 1.5m and a fast and stable response time of less than 1ms. The module consists of a transmitter...

Electronics and water don't usually mix - which is why liquid level sensing projects can be a little challenging. You can DIY a sensor but keeping it clean and un-oxidized...
