Proximity

  1. Exc. VAT: £3.25 Inc. VAT: £3.90
    This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

    These simple switches are the Mechanical Bumper sensor for the SparkFun RedBot, giving you the ability to detect a collision before it really happens. This sensor works by acting as a SPST switch. When the "whisker" bumps into a foreign object it will make contact with a nut next to it, closing the connection and, by default, turning off the motor. By attaching these mechanical bumpers to you robot the whisker will bump something before your robot crashes into it.

    The SparkFun Proximity Sensor Breakout is a simple IR presence and ambient light sensor utilizing the VCNL4040. This type of sensor is often seen in automatic towel and soap dispensers or automatic faucets. With the ability to detect objects qualitatively up to 20cm away, you will be able to detect if something is there and if it is closer or further away since the last reading. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

    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.

    The VCNL4040 is a simple IR presence and ambient light sensor. This sensor is excellent for detecting if something has appeared in front of the sensor. We often see this type of sensor on automatic towel dispensers, automatic faucets, etc. You can detect objects qualitatively up to 20cm away. This means you can detect if something is there, and if it is closer or further away since the last reading, but it's difficult to say it is 7.2cm away. If you need quantitative distance readings (for example sensing that an object is 177mm away) check out the SparkFun 2 meter and 4 meter Time of Flight (ToF) sensors with mm accuracy.

  6. Exc. VAT: £11.08 Inc. VAT: £13.30
    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.

  7. Exc. VAT: £11.50 Inc. VAT: £13.80
    This is the SparkFun RGB and Gesture Sensor, a small breakout board with a built in APDS-9960 sensor that offers ambient light and color measuring, proximity detection, and touchless gesture sensing. With this RGB and Gesture Sensor you will be able to control a computer, microcontroller, robot, and more with a simple swipe of your hand! This is, in fact, the same sensor that the Samsung Galaxy S5 uses and is probably one of the best gesture sensors on the market for the price.

    The SparkFun OpenPIR is a highly customizable Passive Infrared (PIR) sensor based around the NCS36000 PIR controller. Passive infrared (PIR) sensors are able to detect motion in a small/local area –-- they’re the sensor of choice in security systems, home automation and proximity-sensing applications. The OpenPIR allows you to set the sensitivity, trigger time and pulse mode of the motion sensor so you can tailor-fit it to your application!

    The SparkFun Distance Sensor Breakout utilizes the RFD77402 3D ToF (Time of Flight) sensor module from Simblee to give you the most accurate measurements at short range. The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) module to measure the amount of time it takes to bounce off a target. This allows low-cost millimeter readings up to two meters! To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1" spaced pins in case you prefer to use a breadboard.
