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.

The light sensor Bit can turn your circuit on and off by detecting the brightness or darkness of the environment they are in. control your circuit's with light! The amount of light shining on the sensor will change how your circuit behaves. It's a great way to activate your circuit, and is perfect for alarms!

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...

This diffuse reflection infrared photoelectric switch can detect any opaque object within 0-7m( The real detection distance can be greater than 7m in our test)...

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...

Sharp’s GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.
