This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it...

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side.

This diode-transistor photocouplers consist of an LED, optically coupled to a high speed photodetector to transmit electrical signals between circuits while still...

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)...

This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).

Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don’t. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin.

We live in a colorful world, but how much do you really know about color? You eyes may deceive you, while the sensors don’t lie. This AS7341sensor can tell you the...

This new ambient light sensor is packaged in a transparent semisphere case that offers better light-gathering power. The sensor supports a 0-200klx detection range...

This is a small ambient light sensor that acts as an NPN transistor. The more the sensor is exposed to light, the stronger the base bias. Simple to use! Simple breakout board available below.

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...

This is a background suppression photoelectric switch with 15mm-350mm adjustable detection range (can be adjusted by the knob). Its response time is only 0.5ms...

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 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!
